finagle-thrift: Deprecate ThriftClientFramedCodec{Factory}

Problem

ThriftClientFramedCodecFactory is netty3 specific and hinders migration
to netty4.

Solution

Migrate the last usage to the StackClient. This also completes the removal
of internal usages of ThriftClientFramedCodec{Factory} and we can now
deprecate them.
