logger: fail to mount gluster storage shows as warning and not error

[Dafna Ron]

failure to mount gluster storage appears in the cinder volume log as a warning and not an error
since we would basically not be able to create/delete/attach when we fail to mount I think that this should be logged as ERROR and if possible print the trace in the log.

2014-05-08 18:54:45.306 3121 WARNING cinder.volume.drivers.glusterfs [-] Exception during mounting Unexpected error while running command.
Command: sudo cinder-rootwrap /etc/cinder/rootwrap.conf mount -t glusterfs 10.35.64.104:/gluster2-cinder-tshefi /var/lib/cinder/mnt/8f2d3277bf483ae9bae356bd866fed5e
Exit code: 1
Stdout: 'Mount failed. Please check the log file for more details.\n'

It is not appropriate to print a trace for this but we probably should log this as an error rather than a warning.

    Use error instead of warning to log mount exc

    Gluster's driver uses warning to log mount exceptions. This patch
    replaces that warning with an error message.
