promql subcommand

[poy]

As an app developer or operator, I would like to be able to query my metrics via PromQL. Log Cache has PromQL endpoints, however the CLI does not grant access to them.

I would find it quite useful to be able to do something like the following:

cf promql my_metric{source_id="my-app"}

We have created an issue in Pivotal Tracker to manage this:

The labels on this github issue will be updated when the story is started.
