Matt Riedemann 5c5bc57d2b libvirt: remove glusterfs volume driver
Cinder deprecated the GlusterFS volume driver
in Newton and deleted it in Ocata:

I10c576602dd0e65947d1a1af5d04b8ada54f4625

Since it's unused, unmaintained and unsupported in
Cinder we should remove it from the libvirt driver.

This also removes the related configuration options.

A note is left in the code since I'm unsure if anything
relies on checking for the netfs disk source_protocol which
was added at the same time as the glusterfs support in
Ic6dd861b40b692b25df67c9d5b63fd436c690fde.

The ``nova.virt.libvirt.volume.glusterfs.LibvirtGlusterfsVolumeDriver``
volume driver has been removed. The GlusterFS volume driver in Cinder was
deprecated during the Newton release and was removed from Cinder in the
Ocata release so it is effectively not maintained and therefore no longer
supported.
The following configuration options, previously found in the ``libvirt``
group, have been removed:
- ``glusterfs_mount_point_base``
- ``qemu_allowed_storage_drivers``
These were used by the now-removed ``LibvirtGlusterfsVolumeDriver`` volume
driver and therefore no longer had any effect.
