        Store pending invitations to a user's 3pid.

        In addition to the request parameters specified below, an arbitrary
        number of other parameters may also be specified. These may be used in
        the invite message generation described below.

        The service will generate a random token and an ephemeral key used for
        accepting the invite.

        The service also generates a `display_name` for the inviter, which is
        a redacted version of `address` which does not leak the full contents
        of the `address`.

        The service records persistently all of the above information.

        It also generates an email containing all of this data, sent to the
        `address` parameter, notifying them of the invitation.

        Also, the generated ephemeral public key will be listed as valid on
        requests to `/_matrix/identity/v2/pubkey/ephemeral/isvalid`.

        Currently, invites may only be issued for 3pids of the `email` medium.

        Optional fields in the request should be populated to the best of the
        server's ability. Identity servers may use these variables when notifying
        the `address` of the pending invite for display purposes.
