Add ability to generate secrets from CRs

[YannikBramkamp]

Closes #34

[YannikBramkamp]

Notes:

• Had to move unit tests into a single package, as each controller test requires a manager, but I couldn't find a way to terminate a created manager at the end of a test, leading to "this port is already in use" errors.
• Code climate issues are pretty much all related to receiver functions of the operators

@YannikBramkamp Thanks for all your work on this! :+1: I'll happily review this, but since this is a big one, it might take a few days until I get to it... ⏳

@martin-helmich This should be ready now, I hope I didn't forget anything, as there was quite a bit of time between when I started to implement the requested changes and when I finished,
