initial testing for usage reports

[pondrejk]

Problem Statement

SAT-31592

Solution

I added a basic comparison test to check that high level report item keys match with the expected set. For the expected set I use a report output from a fresh satellite.

More tests and fixtures will likely follow as the feature crystalizes. I used Hammer component mainly for convenience, it is not yet clear if this will become a new component
