Implement periodic loop option

Browse source 
Add an interval timing loop for all the grpc scripts that did not already have one. Organized some of the code into functions in order to facilitate this, which caused some problems with local variables vs global ones, so moved the script code into a proper main() function. Which didn't really solve the access to globals issue, so also moved the mutable state into a class instance.

The interval timer should be relatively robust against time drift due to the loop function running time and/or OS scheduler delay, but is far from perfect.

Retry logic is now in place for both InfluxDB scripts. Retry for dishStatusInflux.py is slightly changed in that a failed write to InfluxDB server will be retried on every interval, rather than waiting for another batch full of data points to write, but this only happens once there is at least a full batch (currently 6) of data points pending. This new behavior matches how the autocommit functionality on SeriesHelper works.

Changed the default behavior of dishStatusInflux.py to not loop, in order to match the other scripts. To get the old behavior, add a '-t 30' option to the command line.

Closes #9

`parseJsonHistory.py` operates on a JSON format data representation of the protocol buffer messages, such as that output by [gRPCurl](https://github.com/fullstorydev/grpcurl). The command lines below assume `grpcurl` is installed in the runtime PATH. If that's not the case, just substitute in the full path to the command.
All the tools that pull data from the dish expect to be able to reach it at the dish's fixed IP address of 192.168.100.1, as do the Starlink [Android app](https://play.google.com/store/apps/details?id=com.starlink.mobile) and [iOS app](https://apps.apple.com/us/app/starlink/id1537177988). When using a router other than the one included with the Starlink installation kit, this usually requires some additional router configuration to make it work. That configuration is beyond the scope of this document, but if the Starlink app doesn't work on your home network, then neither will these scripts. That being said, you do not need the Starlink app installed to make use of these scripts.

The scripts that don't use `grpcurl` to pull data require the `grpcio` Python package at runtime and generating the necessary gRPC protocol code requires the `grpcio-tools` package. Information about how to install both can be found at https://grpc.io/docs/languages/python/quickstart/

## Usage
Of the 3 groups below, the grpc scripts are really the only ones being actively developed. The others are mostly by way of example of what could be done with the underlying data.
### The JSON parser script
`parseJsonHistory.py` takes input from a file and writes its output to standard output. The easiest way to use it is to pipe the `grpcurl` command directly into it. For example:
```
grpcurl -plaintext -d {\"get_history\":{}} 192.168.100.1:9200 SpaceX.API.Device.Device/Handle | python parseJsonHistory.py
@ -28,7 +32,11 @@ python parseJsonHistory.py -h
When used as-is, `parseJsonHistory.py` will summarize packet loss information from the data the dish records. There's other bits of data in there, though, so that script (or more likely the parsing logic it uses, which now resides in `starlink_json.py`) could be used as a starting point or example of how to iterate through it. Most of the data displayed in the Statistics page of the Starlink app appears to come from this same `get_history` gRPC response. See the file `get_history_notes.txt` for some ramblings on how to interpret it.
The other scripts can do the gRPC communication directly, but they require some generated code to support the specific gRPC protocol messages used. These would normally be generated from .proto files that specify those messages, but to date (2020-Dec), SpaceX has not publicly released such files. The gRPC service running on the dish appears to have [server reflection](https://github.com/grpc/grpc/blob/master/doc/server-reflection.md) enabled, though. `grpcurl` can use that to extract a protoset file, and the `protoc` compiler can use that to make the necessary generated code:
The one bit of functionality this script has over the grpc scripts is that it supports capturing the grpcurl output to a file and reading from that, which may be useful if you're collecting data in one place but analyzing it in another. Otherwise, it's probably better to use `dishHistoryStats.py`, described below.

Then move the resulting files to where the Python scripts can find them.
Then move the resulting files to where the Python scripts can find them in its import path, such as in the same directory as the scripts themselves.
Once those are available, the `dishHistoryStats.py` script can be used in place of the `grpcurl | parseJsonHistory.py` pipeline, with most of the same command line options.

```
python3 parseHistoryStats.py
```
To collect and record summary stats every hour, you can put something like the following in your user crontab:
By default, `parseHistoryStats.py` (and `parseJsonHistory.py`) will output the stats in CSV format. You can use the `-v` option to instead output in a (slightly) more human-readable format.
To collect and record summary stats at the top of every hour, you could put something like the following in your user crontab (assuming you have moved the scripts to ~/bin and made them executable):
```
00 * * * * [ -e ~/dishStats.csv ] || ~/bin/dishHistoryStats.py -H >~/dishStats.csv; ~/bin/dishHistoryStats.py >>~/dishStats.csv
```
`dishHistoryInflux.py` and `dishHistoryMqtt.py` are similar, but they send their output to an InfluxDB server and a MQTT broker, respectively. Run them with `-h` command line option for details on how to specify server and/or database options.
`dishDumpStatus.py` is even simpler. Just run it as:
`dishStatusCsv.py`, `dishStatusInflux.py`, and `dishStatusMqtt.py` output the status data instead of history data, to various data backends. The information they pull is mostly what appears related to the dish in the Debug Data section of the Starlink app. As with the corresponding history scripts, run them with `-h` command line option for usage details.
By default, all of these scripts will pull data once, send it off to the specified data backend, and then exit. They can instead be made to run in a periodic loop by passing a `-t` option to specify loop interval, in seconds. For example, to capture status information to a InfluxDB server every 30 seconds, you could do something like this:
```
python3 dishStatusInflux.py -t 30 [... probably other args to specifiy server options ...]
```
Some of the scripts (currently only the InfluxDB ones) also support specifying options through environment variables. See details in the scripts for the environment variables that map to options.
### Other scripts
`dishDumpStatus.py` is a simple example of how to use the grpc modules (the ones generated by protoc, not `starlink_grpc.py`) directly. Just run it as:
```
python3 dishDumpStatus.py
```
and revel in copious amounts of dish status information. OK, maybe it's not as impressive as all that. This one is really just meant to be a starting point for real functionality to be added to it.

`dishStatusCsv.py`, `dishStatusInflux.py`, and `dishStatusMqtt.py` output the same status data, but to various data backends. As with the corresponding history scripts, run them with `-h` command line option for usage details.
Possibly more simple examples to come, as the other scripts have started getting a bit complicated.
## To Be Done (Maybe)
There are `reboot` and `dish_stow` requests in the Device protocol, too, so it should be trivial to write a command that initiates dish reboot and stow operations. These are easy enough to do with `grpcurl`, though, as there is no need to parse through the response data. For that matter, they're easy enough to do with the Starlink app.
Proper Python packaging, since some of the scripts are no longer self-contained.
## Other Tidbits
The Starlink Android app actually uses port 9201 instead of 9200. Both appear to expose the same gRPC service, but the one on port 9201 uses an HTTP/1.1 wrapper, whereas the one on port 9200 uses HTTP/2.0, which is what most gRPC tools expect.
