Add ability to include Protobufs in ObjectWritable

                 Key: HADOOP-7379
                 URL: https://issues.apache.org/jira/browse/HADOOP-7379
             Project: Hadoop Common
          Issue Type: Improvement
          Components: io, ipc
    Affects Versions: 0.23.0
            Reporter: Todd Lipcon
            Assignee: Todd Lipcon
             Fix For: 0.23.0

Per HDFS-2060, it would make it easier to piecemeal switch to protocol buffer based data structures
in the wire protocol if we could intermix the two. The IPC framework currently provides the
concept of "engines" for RPC, but that doesn't easily allow mixed types within the same framework
for ease of transition.

I'd like to add the cases to ObjectWritable to be handle subclasses of {{Message}}, the superclass
of codegenned protobufs.
