[HWKMETRICS-168] fix post merge errors and disable integration test

There were some changes need as a result of HWKMETRICS-114 which made the tenant id part of MetricId. The REST integration test for fetching counters is disabled for now. Rates are calculated every minute (as of right now). We do not want to have a test literally spin for several minutes waiting for rates to be generated. We need a way to use RxJava's TestScheduler for REST integration tests. I am going to createa spearate ticket for this because I think it will involve a bit of work.
