WIP: cFS app demonstration

[ivanperez-keera]

This PR is WIP.

It's a demonstration of the monitoring use case using cFS.

[ivanperez-keera]

The status at the moment is:

• It contains the three apps.
• The Copilot app uses the same monitor as in the other use case.
• The apps are able to receive and send messages.
• Copilot is detecting messages to/from both apps correctly.
• The user is able to adjust the delay of the lights app with a message from the ground station.

Sample command sent from ground station:

./cmdUtil --host=localhost --port=1234 --endian LE --pktid=0x1A78 -C 0 --long=1

Output seen in cFS (with extra debug messages being printed by the Copilot app):

Copilot detected a command for the lights app to change the lights
EVS Port1 1980-012-14:24:11.18919 66/1/SWITCH_APP 14: SWITCH: requested to change light status to 1
Copilot detected an event from the lights app with the light change
EVS Port1 1980-012-14:24:11.58930 66/1/LIGHTS_APP 15: LIGHTS: lights changed
