geo-rep: Fix add user in mountbroker user management

The CLI 'gluster system:: execute mountbroker user <USERNAME> <VOLUMES>'
to set volumes associated with a user replaces existing user and associated
volumes upon setting with existing user. This patch fixes it by appending
the volumes if the user already exists.

It also introduces following CLI to remove volume for a corresponding user.

'gluster system:: execute mountbroker volumedel <USERNAME> <VOLUME>'
<USERNAME>: username
<VOLUME>: comman separated list of volumes to delete

If it is the last volume to be deleted associated with the user,
it will delete the user as well as it doesn't make sense to keep
only user without volumes associated.
