Dependency injection

[Yaremadzulynsky]

Description

What was completed, changed, or updated?

All dependency objects used by TelemetryManager (e.g. GroundStationCommunication) are now created in SystemManager before the TM object. Dependencies are passed directly to the TM constructor.

All state data pointers used by TM have been organized to a struct.

Why was this done (if applicable)?

TM can now be created from mock instances for testing.
The order of object construction can be changed, so we can wait until we have all dependencies ready before initializing a TM object.
TM objects can potentially be made outside of SystemManager

Testing

What unit tests were used to validate the code?

• tools.ps1 compile test

Great work!

[Yaremadzulynsky]

Awesome. One note I have is that the SM constructor is starting to look a little cluttered with TM stuff. What we could do is make a function in the SM cpp file called something like setupTM() which will do the TM setup stuff, then call tm->init() after everything is set up.

LGTM 😃
