+++ This bug was initially created as a clone of Bug #1414346 +++

Description of problem:

Quota is enabled,and limit-usage is set on certain directories. After upgrade
from 3.7.9 to latest quota list command shows "No quota configured on volume
repvol "

Steps to Reproduce:
1. Create 2*2 dist-repvol vol on 3.7.9
2. Enable quota and set limit-usage and limit-object
3. Do fuse mount and create some date on mount point
4. Now do in-server upgrade of system .
5. after upgrade run quota vol list command

Actual results:

gluster v info shows quota is on 
however quota list command shows "quota: No quota configured on volume "

Expected results:

quota list command should work 

It was noticed that with op version bump up the quota conf file is updated and
the limits stored in this file get lost. 

This issue is hit in 2 scenarios:
1) when we upgrade from 3.6 to 3.7 (where the quota.conf needs an upgrade)
2) When the upgrade happens from 3.7 or more to higher version (where no
quota.conf upgrade is needed)

    Fixes upgrade issue in quota.conf

    When an op-version bump up is done the glusterd_store_quota_config
    upgrades the quota conf file, although overwriting the same later
    which leaves out all gfid entries. While this is warranted for
    enable opcode, for upgrade we need to retain gfids. So for upgrade
    opcode, we return once the upgrade is done.
