Remove unused code

[ramperher]

build-depends: rh-nfv-int/nfv-example-cnf-deploy#51

This code is legacy one that is no longer used:

• cnf-app-mac-fetch (cnf-app-mac-operator) - we still have references to this : https://github.com/rh-nfv-int/cnf-app-mac-fetch, but in fact, the current cnf-app-mac-operator is the evolution of that code, we no longer need this
• cnf-run configmap (testpmd-operator) - even though this file is loaded by using a configmap, we never use it; we rely on the Python scripts provided in the testpmd image

• SUCCESS https://www.distributed-ci.io/jobs/04e09070-c0b9-4995-adf5-910d425f79bd/jobStates

Check is working, the removed code is not affecting, this is ready for review
