Description of problem:
shard-size has now been embedded into the code and the default is set as 64MB through the bug fix https://bugzilla.redhat.com/show_bug.cgi?id=1468969 and it is no longer required to set it explicitly again from cockpit+gdeploy. Raising this bug so that it can be removed from cockpit+gdeploy.

Version-Release number of selected component (if applicable):
cockpit-ovirt-dashboard-0.10.8-2.2.ovirt41.el7ev.noarch

How reproducible:
Always

Steps to Reproduce:
1. Install HC with latest glusterfs bits which is 3.1.3
2. Now run through cockpit gdeploy to setup gluster config.
3. 

Actual results:
In the generated config file we can see that shard-block-size is explicitly set to 64MB. 

key=features.shard-block-size
value=64MB

Expected results:
shard-block-size parameter can now be removed from the generated gdeploy conf file.
