Breaking API Changes

finagle-core: As part of a move away from encoding/decoding in the Netty pipeline, removed
FrameEncoder and FrameDecoder types, found in c.t.f.codec. RB_ID=847716
finagle-core: Delete IdleConnectionFilter, which is no longer hooked up in the server, and
no longer seems to be useful. RB_ID=856377
finagle-core: Remove deprecated methods from c.t.f.builder.ClientBuilder RB_ID=864622
- connectionTimeout, use tcpConnectTimeout
- expFailFast, use failFast
- buildFactory, use other buildFactory methods
- build, use other build methods
finagle-exp: Abstract out parts of the DarkTrafficFilter for potential re-use.
We also canonicalize the DarkTrafficFilter stats scope which changes from
"darkTrafficFilter" to "dark_traffic_filter". E.g.:
"dark_traffic_filter/forwarded", "dark_traffic_filter/skipped", and
"dark_traffic_filter/failed". RB_ID=852548
finagle-mysql: Mysql has been promoted out of experimental. Please change all
references of com.twitter.finagle.exp.{M,m}ysql to com.twitter.finagle.{M,m}ysql
finagle-redis: Server-side support for Redis is removed. See this finaglers@ thread
(https://groups.google.com/forum/#!topic/finaglers/dCyt60TJ7eM) for discussion.
Note that constructors for Redis commands no longer accept raw byte arrays.
RB_ID=848815
finagle-redis: Redis codec (i.e., c.t.f.Codec) is removed. Use c.t.f.Redis.client
instead. RB_ID=848815

finagle-core: Expose metrics on util's default FuturePool implementations
unboundedPool and interruptibleUnboundedPool:
"finagle/future_pool/pool_size", "finagle/future_pool/queue_size",
"finagle/future_pool/active_tasks", and "finagle/future_pool/completed_tasks".
RB_ID=850652
finagle-thrift: maxThriftBufferSize is now tunable via parameter for Thrift
servers. It previously only was for ThriftMux servers. RB_ID=860102
finagle-core: Mux Clients now propagate the number of times the client retried
the request in the request's c.t.f.context.Context, available via
c.t.f.context.Retries. RB_ID=862640

finagle-http: HttpTransport now eagerly closes client connection after
processing non-keepalive requests.
finagle-redis: c.t.f.redis.Client now uses the pipelining dispatcher. RB_ID=848815
finagle-serversets: c.t.f.serverset2.Stabilizer no longer uses a timer to implement
stabilization periods if the periods are 0 seconds long. RB_ID=861561
finagle-core: 'c.t.f.Failure' has a new flag, Rejected, to indicate that a given request was
rejected. All Failures generated with the Failure.rejected constructor are flagged Rejected and
Restartable. RB_ID=863356
finagle-core: c.t.f.FixedInetResolver now optionally retries failed DNS
lookups with provided backoff, and c.t.f.serverset2.Zk2Resolver uses this
retry functionality infinitely, exponentially backing off from 1 second to
5 minutes. RB_ID=860058
