Muscle manager: check timelines

[maarten-ic]

This PR adds:

1. Timeline checking by the muscle manager: run ymmsl.v0_2.resolve_timelines() before starting the simulation to ensure that timelines are connected correctly.
2. Return the timeline of a component when it registeres with the muscle manager. We'll need this for the reducer filters in an upcoming PR.

To make this all work out, I also needed to update:

• The muscle3_tester:
  • Timeline annotations added to the ports of the tester instance.
  • If the tested component doesn't have F_INIT connections, we add a Conduit to its muscle_settings_in port to make these timeline annotations work.
    This was needed in order to connect to an O_F port of an instance without F_INIT ports: if we do not connect muscle_settings_in, the tested component would live in the root timeline and we would not be able to connect the O_F port to an S port of the tester. By connecting the muscle_settings_in port, the tested component lives in the correct subtimeline.
  • Patch some shutdown logic in the muscle_tester to shut down faster in case the tested component crashes or doesn't start.
• Some unit tests for registering components that would refer to a test_instance_id that was not part of the Configuration.

Alright, this works. One open question but no need to implement that now I think, unless it's easy and makes sense. I'll leave that to @IrisvdWerf because it's your code.
