openonuAdapterGo - robot test for MIB audit

A test case checking MIB audit has to be created.

Openonu adapter has to be set up with a mib audit period e.g. for one minute.
Any scenario (ATT, DT or TT) has to be brought up (e.g. running sanity check). After a certain time period the MDS counter has to be invalidated (already implemented in BBSIM) . Mib audit has to detect wrong MDS counter and start MIB Reset and new provisioning of ONU. Verification of usual system states afterwards and ONU connection state.
Test case should run for all possible scenarions (ATT, DT and TT) and single ONU as well as multiple ONU/OLT.

Test case could be used for manual testing first, but integration into some pipeline later on.

Precondition for automated in pipeline is https://jira.opencord.org/browse/VOL-3785.
