Add latency test to diagnostics report

[jselig-rigetti]

Users have reported unexpected slowness while using a live QPU that seemed to be due in part to strangely high latency in gRPC requests during program translation, submission for execution, and results retrieval.

A latency detection utility in the diagnostics report could help diagnose these issues.

Currently the diagnostics report looks like the following:
