Added metrics for production readiness.

Browse Source 
[ Merge of http://go/wvgerrit/151749 ]

Extended CryptoSession for recording the result of
OEMCrypto_ProductionReady().

Only OEMCrypto_SUCCESS is considered "production ready".  With the
exception of OEMCrypto_ERROR_NOT_IMPLEMENTED, any other result is
vendor-specific and indicates not being production ready.

Test: metrics_collections_unittest
