Previously, we did not have a license request latency metric. This is a notable limitation in our metrics. This adds a metric that captures the timing between a GenerateKeyRequest and an AddKey operation. Bug: 72994956 Test: New unit tests. Google Play Change-Id: If99c187399c02f9b5d4c355732af7588bbbefb11
