Description of problem:
------------------------
With the effect of the bug BZ 1424934, the most of the required volume options are made available with 'virt' profile in Gluster.

There are most of the options which are again set redundant.
Remove these options from generated gdeploy config file

Version-Release number of selected component (if applicable):

cockpit-ovirt-dashboard-0.10.7-0.0.10

How reproducible:
-----------------
Always

Steps to Reproduce:
--------------------
1. Finish the first 4 steps of 'Hosted Engine deployment with Gluster'
2. Observe the generated gdeploy config file in the final tab

Actual results:
---------------
Gluster volume options are set redundant, although the virt profile set the same options

Expected results:
------------------
Remove the redundant option set by gdeploy key&volume options in 'volume' section.
