Some basic structure.

Added some structures, enums, etc. to hold the data we will need.
Added an initialize_apis that only looks for config files so far.

TODO:
Use zbus to create our service, register the name, etc. to start.
Decide on a config file format (maybe after getting some zbus
details fleshed out and knowing better what will fit well)
Add error messages and don't fail on errors, just log them.
