Prefix micrometer metric tags with meter names

Browse Source 
This is what is recommended by the observability
team in terms of tag naming with micrometer 1.10+
for consistency between both metrics and tracing.

In #4065, only some metrics have been updated to
follow this tag naming convention, but not all of
them. This commit updates all metrics in a similar
way for consistency.

Related to #4065 and #4098.
