Recipe PR: symfony/recipes#1374

Added a new notifier bridge for Matrix Synapse.

Whats implemented in this?
- sends message to roomID when roomID or userID or roomAlias (see above) is given as recipient
- fetches roomID of private room when userID is given as recipient, if no room is available it will be created and the recipiant will be invited to join
- fetches roomID when roomAlias is given as recipient

Whats not implemented at the moment?
- end-to-end encryption, all messages will be unencrypted even if E2E enabled in the room.
