Review request for mesos, Adam B and Niklas Nielsen.


Changes
-------

Addressed Joris's comment.


Bugs: MESOS-2558
    https://issues.apache.org/jira/browse/MESOS-2558


Repository: mesos


Description
-------

The new preferred location for FrameworkID is FrameworkInfo.id. This patchset 
achieves this goal by incrementally deprecating other locations for FrameworkID.

Here is a plan to deal with the upgrade path:

For this release (N), we still keep setting RunTaskMessage::framework_id
  - this would handle older Slaves with newer Master.
  - added code to handle it being unset in the Slave (handles older
    Master with newer Slaves).

In the following release (N+1), stop reading/setting 
RunTaskMessage::framework_id
  - the previous version would handle the unset case.

In release N+2, remove the field altogether:
  - the previous release is not setting/reading it.
