[nasa/nos3#838] OpenC3 Gem Autoloading and Python Scripting

[kevincbruce]

Summary:
Seeks to greatly improve OpenC3 COSMOS 6.3.0 integration into NOS3 with the following major updates:

• Consistent Automatic Building and Loading of .gem files with all the ruby and python files needed present and in the folders expected by COSMOS 6.3.0's gem building tools.
• Automatic cleanup of gems, buckets, and other residuals with a make clean, so that new gem builds can be loaded cleanly.
• System tests for the Sample App translated from ruby into Python for COSMOS 6.3.0, with minor tweaks/adaptations to ensure they run smoothly and consistently. These may serve as a rough guide for the translation of other apps system tests when we get to them in the future.

The biggest changes are to the gsw_openc3_clean/build/launch.sh files, the addition of python versions of the sample_lib, sample_test, sample_app_test, sample_ast_test, and sample_device_test files, and minor updates to the nos3_simulator.xml (commented line for easy switching between COSMOS 4.5 and COSMOS 6.3 settings for truth42sim interface).

How to test?

• git pull
• git checkout nos3#838-openc3-scripting, git submodule sync, git submodule update --init --recursive
• If not updated to the dev/1.7.5 version of the containers (particularly 42), run a make uninstall and make prep
• Go into nos3-mission.xml and update line 12 to openc3
• Go into nos3-simulator.xml and comment out line 518 and uncomment line 519 (so your cosmos hostname for truth42sim is set to active-gs to hook to the proper COSMOS 6.3 container). I have tested with the radio set to occulted and delay on. System tests do not use radio, so should not effect them, but did verify the radio line of sight feature works in openc3's radio interface.
• make clean, make config, make, make launch
• On launch, you may need to refresh firefox a few times to get openc3 up properly. Put in whatever password you want when prompted. In the terminal tab where you ran make launch, you should, after a minute or two, see the gem upload process start. Verify that once it is done spamming to the terminal, you get an upload successful or similar message, rather than an upload failure. Then, wait several minutes until all your interfaces show up as connected in the Command Telemetry Server tab of OpenC3 (may require refreshes to see, and a refresh once all interfaces (and thus microservices, as the interfaces load last) are loaded, or else some options may not show up in the menu/drop down on the left side.
• Once in a steady state, switch to the Script Runner tab, in the file menu select Open File, and navigate to SAMPLE_DEBUG/scripts/sample_test.py (note, the ones in SAMPLE_RADIO should work as well, but will use SAMPLE_DEBUG, not the radio).
• Once loaded, it should switch to the test runner interface. On the top option (test suite level), click Start. Verify the test runs successfully without errors. Run a few more times to verify.
• Run a make stop to bring things down
• Run a make launch to verify it launches again without attempting to overwrite the existing gem file. Feel free to test functionality again once it is up. It should come up much quicker with the gem already set up.
• When done, run make stop to bring NOS3 down

Submodule PRs and actions prior to closing this:

• sample PR: [nasa/nos3#838] openc3 scripting nasa-itc/sample#38
• I believe we want to merge this after the 1.7.5 release, but that is up to the discretion of the team.

Closes #838
