New Features

• finagle-core: Introduce a new ResponseClassifier ('IgnoreIRTEs') that treats com.twitter.finagle.IndividualRequestTimeoutExceptions as ResponseClass.Ignored. This response classifier is useful when a client has set a super low RequestTimeout and receiving a response is seen as 'best-effort'. e897bd67
• finagle-mysql: Introduce support of opportunistic TLS to allow mysql clients with enabled TLS to speak over encrypted connections with MySQL servers where TLS is on, and fallback to plaintext connections if TLS is switched off on the server side. e02495aa
