Create Prototype of "OCM Controller provider" for MCP

[morri-son]

Description
The OCM controllers should be available as provider in openMCP. Since openMCP is not GA right now, the implementation should be done as Prototype, exception workarounds where required.

Sub-Topics for the various tasks to be created on demand.

@jakobmoellerdev I guess we can close this one as there is a similar Issue on the CoLa backlog already.
