LGTM, just minor nit for tests.

The only potential question is around compatibility for this. For client_golang we should be fine, we don't surface this option to users.
But for potentially downstream common users this might be explictly breaking (compile error). I don't know about any evidences of wide usage, also it could be a damaging option (renaming metrics), so I vote we kill it.

Following this discussion regarding OM unit support in client_golang, this PR removes the optional unit flag and the related logic that would automatically change the metric name if the UNIT field was populated but the unit not already included in the metric name. This is needed to complete the afore mentioned client_golang PR. cc @bwplotka .
