glusterd: Add option to get all volume options through get-state CLI

This commit makes the get-state CLI capable to returning the values
for all volume options for all volumes. This is similar to what you
get when you issue a `gluster volume get <volname> all` command.

This is the new usage for the get-state CLI:

 # gluster get-state [<daemon>] [[odir </path/to/output/dir/>] \
[file <filename>]] [detail|volumeoptions]
