[Ramana Raja]

glusterfs (NFS) driver CI fails always as it cannot create shares, and on further search of the logs found that manila-scheduler log fails to find a host to create shares on,

Pasting the relevant screen-m-sch log,

    Manila: Fix share_type in glusterfs (NFS) CI

    During glusterfs (NFS) CI run, the extra spec "snapshot_support" used
    for the default share-type is set to "True" even though the CI tests
    the glusterfs backend with directory based share layout scheme that
    does not support snapshot. So set the extra_spec to False which would
    allow the Manila scheduler to pick up the glusterfs backend as a valid
    host.
