Read-only shares in Quobyte Backend are RW indeed

[Silvan Kaiser]

The string `access_level` won't ever be equal to `ro`as implemented in quobyte.py

Fix should be : retrieve the `access_level` value from the `access` dict and compare the result

[Valeriy Ponomaryov (vponomaryov)]

It is security issue for QuoByte driver that should be fixed, so setting status "critical" and RC1 candidate.

    Make Quobyte shares actually read-only when requested

    The string `access_level` won't ever be equal to `ro` in Quobyte Driver.
    Do the right thing:
    retrieve the `access_level` value from the `access` dict and
    compare the result, as most likely intended but incorrectly implemented
    and not tested. Also add the missing test.
