[ Merge of http://go/wvgerrit/88016 ] In the event of an LRU replacement event on AddKey, we gather some metrics on what the state of the usage table is and some info on the the entry that was removed. Metrics collected: - How many usage info (streaming license) in the table - How many offline licenses in the table - What type of entry was evicted from the table - How stale (time since last use) was the evicted entry This also enables unit tests for marshalling the metrics into proto message on Android unit test. Bug: 135046978 Test: Android and Linux unit tests Change-Id: If8e562ae6f98270a0e6c5aa4251127ce9b79a8b0
