@spkrka SemanticFolsomMetricsTest::testRegisterOutstandingRequestsGauge is failing with this change.
Here's a gist to fix and improve that test: https://gist.github.com/amirhadadi/6e4580c7e91887e53f0993d30e619674

@spkrka the motivation is to have metrics that will allow identifying misbehaving memcached nodes.
There's also another related issue - the disconnect reason in DefaultRawMemcacheClient does not contain the offending node, which can be very helpful in identifying misbehaving nodes.
