The commit message is wrong in the below. It misrepresents.

>From the issue:

The -1 is because no case was made for why we need this feature. Usually
folks show up w/ some numbers or a graph or some reasoning as to why
something is needed. In here there is none of that; there is 'certain use
cases' that go unspecified and then when pushed, some rambling about ambari
metrics server with no timelines or measure of what is being addressed or
fit criteria as to what would make ambari-case happy.
