---------------------------------------

             Summary: IGFS: Introduce separate processor for "move" operation when parent
is the same for source and destination.
                 Key: IGNITE-3308
                 URL: https://issues.apache.org/jira/browse/IGNITE-3308
             Project: Ignite
          Issue Type: Sub-task
          Components: IGFS
    Affects Versions: 1.6
            Reporter: Vladimir Ozerov
            Assignee: Vladimir Ozerov
             Fix For: 1.7


Consider the following operation: {{move("/parent/a", "parent/b")}}.
In this case we will call two entry processors: {{IgfsMetaDirectoryListingRemoveProcessor}}
to unlink "a" and {{IgfsMetaDirectoryListingAddProcessor}} to link "b". 

Instead, we should call only a single processor as source and destination keys are the same.
This will save network traffic and possibly decrease number of remote calls.
