mount.glusterfs: getopts support and cleanup

Browse Source 
This patch is an attempt to provide some much needed
cleanup for future maintenance of `mount.glusterfs`

- Add checks for command failures
- Spliting large code into subsequent simpler functions
- Standardized variables
- use 'bash' instead of 'sh' - since string manipulation
  and variable handling is far superior
- Overall code cleanup and Copyright change to Red, Hat Inc.
- Add new style of mounting with a comma separated list
  ~~~
  $ mount -t glusterfs <IP1/HOSTNAME1>,<IP2/HOSTNAME2>,..<IPN/HOSTNAMEN>:/<VOLUME> <MNT>
  ~~~
- Update age old `manpage` with new options :-)
