HADOOP-18487. Make protobuf 2.5 an optional runtime dependency. (#4996)
Protobuf 2.5 JAR is no longer needed at runtime. 

The option common.protobuf.scope defines whether the protobuf 2.5.0
dependency is marked as provided or not.

* New package org.apache.hadoop.ipc.internal for internal only protobuf classes
  ...with a ShadedProtobufHelper in there which has shaded protobuf refs
  only, so guaranteed not to need protobuf-2.5 on the CP
* All uses of org.apache.hadoop.ipc.ProtobufHelper have
  been replaced by uses of org.apache.hadoop.ipc.internal.ShadedProtobufHelper
* The scope of protobuf-2.5 is set by the option common.protobuf2.scope
  In this patch is it is still "compile"
* There is explicit reference to it in modules where it may be needed.
*  The maven scope of the dependency can be set with the common.protobuf2.scope
   option. It can be set to "provided" in a build:
       -Dcommon.protobuf2.scope=provided
* Add new ipc(callable) method to catch and convert shaded protobuf
  exceptions raised during invocation of the supplied lambda expression
* This is adopted in the code where the migration is not traumatically
  over-complex. RouterAdminProtocolTranslatorPB is left alone for this
  reason.
