Add Crazyswarm2 to regular scheduled tests

[knmcguire]

This add crazyswarm2 to the scheduled tests in the crazyflie stablab:

• This replaces Crazyswarm1 which is no longer maintained with Crazyswarm2
• It uses the stablab board with regular crazyflies and no longer the swarmboard, as that consists of deprecated roadrunners with external antenna's (too of an ideal situation)
• It now evaluates 5 instead of 10 systems (for stability reasons currently handled by Crazyswarm2
• The crazyswarm2 tests no longer flashes the new firmware as that should be done with the crazyflie stab tests 2 hours before, but it still resets the Crazyflies
• It also currently only tests the crazyflie server of the CPP backend and the simple set_param example (which is part of the Crazyswarm. The launch file automatically closes all executables as soon as the set_param node is finished.
• The timeout is set to 10 minutes as this is a test that should take no longer than 5 minutes. It usually gets stuck on the server being unable to find all crazyflies.
