btrfs-progs: add quota-related info to usage messages
Extending usage messages with some info on the quota functionality: - The -i option of "subvol create" and "subvol snapshot" was not documented - The -c option of "qgroup limit" is the default option - The "qouta rescan" command is not yet implemented, while it should be executed after enabling quota on a non-empty filesystem.
