      Connection context is now sent as a rpc header wrapped protobuf.

      Description

      After HADOOP-9421, all RPC exchanges (including SASL) are wrapped in RPC headers except IpcConnectionContext, which is still raw protobuf, which makes request pipelining (a desirable feature for things like HDFS-2856) impossible to achieve in a backward compatible way. Let's finish the job and wrap IpcConnectionContext with the RPC request header with the call id of SET_IPC_CONNECTION_CONTEXT. Or simply make it an optional field in the RPC request header that gets set for the first RPC call of a given stream.
