WHAT
Update metrics to reflect below
https://docs.google.com/document/d/1hS9YX2RNtLIUaLojWtcV7MymHMVyhlJUxxcdK0r9Gvc/edit

HOW
With regard to the rhoam_version metric. If we can not drop labels we may need to create a new metric
with the cut down number of labels.

Add comments to all metrics being sent to telemeter to highlight to folks that adding labels will
require sign off from telemeter as it will affect cardinality

TESTS
update unit tests

DONE

• metrics modified to match requires in the above linked document
• cardinality of updated metrics match values stated in above linked document
