Description

ATSv2 allows users to write its metrics using TimelineMetric. But, there is no field to tell what is the UNIT of published metric. This is very difficult when metrics are read.

I propose to add UNIT for TimelineMetric so that once user can use this field to tell what is the unit of published metric. May be this can be optional for few kind or metrics where unit is not required say CPU. But definitely there should be a way to set units while publishing the entities.
