cli : provide prompt for the nfs-ganesha disable cli

Presently, when we are executing the command "gluster nfs-ganesha disable",
the disable of nfs-ganesha cluster starts working whereas, in some cases
the user may not want to disable the cluster. So we shall let him know by
giving a prompt to let him say "yes or no" for going ahead with the disable
procedures.
