#### METADATA
The old ShadowIRCD implementation of METADATA used `ADD` and `DELETE` verbs for
adding and deleting metadata to channels and clients. This, in practice looks
something like:
<<< :45X ENCAP * METADATA ADD 1NRAAAABR OPERSTRING :is an IRC Administrator
<<< :45X ENCAP * METADATA DELETE 1NRAAAABR OPERSTRING
Functionality is identical to the new `SET` and `CLEAR` verbs, but this deviates
from the spec by being **only** a server to server command. Support for client
to server and server to client metadata setting/getting will come in a future
version of elemental-ircd.
