Review request for mesos, Jie Yu and Jan Schlicht.


Bugs: MESOS-8058
    https://issues.apache.org/jira/browse/MESOS-8058


Repository: mesos


Description
-------

The function 'applyCheckpointedResources' assumed that the resources
to modify had no previous operations applied to them, but already
implemented the functionality to "undo" operations on resources in
order to identify the resource an operation is applied on.

This change extracts this functionality into a separate function, and
now undos operations on the source resources as well. This allows
callers to pass resources which had operations applied to them to
'applyCheckpointedResources'. Currently all source resources are still
plain in that no operations had been applied to them. We will change
calling code in a later patch.
