Description of problem:
---------------------------------------
When a volume is deleted from gluster CLI, and another volume having the same name is created immediately, the Console fails to display the changes correctly.

Version-Release number of selected component (if applicable):
Red Hat Storage Console Version: 2.1-qa18.el6ev 

How reproducible:
Always

Steps to Reproduce:
1. For an existing volume, run the following command from gluster CLI - 
   gluster volume delete <vol-name>;gluster volume create <vol-name> <new-brick>
   (vol-name for both deletion and creation have to be the same)
  
Actual results:
The Events tab displays a message which indicates that the bricks that were part of the volume (before its deletion from CLI) were removed from CLI. It fails to add the new bricks and show changes in volume options (after creation of the new volume). If the newly created volume is started from the CLI, that change is seen in the GUI.

The following is seen in the engine logs -

Expected results:
The Console should first say that the volume was removed and then say that a volume has been created and display the correct volume details (corresponding to the new volume).
