TMC component testing

Once TMC has reached a stage where it can be deployed independently we need to start looking at TMC testing and make sure that it is mature enough to guarantee a robust integration. 

The result of this feature should be that we can reliably reproduce and test the integration of all TMC components, in a component level integration environment. This should be deployed on the same base platform as SKAMPI, but executing a different set of tests, that verify the standalone functionality of the TMC.

Mocks and emulators shall be introduced as necessary for external elements. 

Any development of new TMC components shall be verified at this level before integration into SKAMPI. 

A possible source of inspiration is the sdp-integration repository, which is built with these principles in mind: https://gitlab.com/ska-telescope/sdp/ska-sdp-integration
