Port module to the new interface

Synapse introduced new generic modules system in v1.37.0. For more details see:

• https://element-hq.github.io/synapse/latest/upgrade.html#upgrading-to-v1390
• https://element-hq.github.io/synapse/latest/modules/porting_legacy_module.html
• https://element-hq.github.io/synapse/latest/modules/password_auth_provider_callbacks.html

The methods used for user registration and email authentication are temporarily removed until those are also ported to work with the new module interface.

 And you will be good to go!
-
-Email Authentication
-~~~~~~~~~~~~~~~~~~~~
-
-While this module helps in authenticating with diaspora, we need to set up mxisd_ for supporting
-authentication through email.
-
-Installation
-^^^^^^^^^^^^
-
-Follow the instructions `here <https://github.com/kamax-io/mxisd/blob/master/docs/getting-started.md#install>`_
-
-Configuration & Setup
-^^^^^^^^^^^^^^^^^^^^^
-
-Follow `this <https://github.com/kamax-io/mxisd/blob/master/docs/getting-started.md#configure>`_.
-
-Basically, if you used the debian package, you just need to set up the ``matrix.domain`` first.
-
-And then, add these lines to ``mxisd.yaml``:
-
-.. code:: yaml
-
-    sql:
-      enabled: true
-      type: mysql
-      connection: "//<HOST>/<DATABASE>?user=<USERNAME>&password=<PASSWORD>"
-      identity:
-        type: 'uid'
-        query: "select (case when ?='email' then username else null end) as uid from users where email=?"
-
-Where ``<HOST>``, ``<DATABASE>``, ``<USERNAME>`` and ``<PASSWORD>`` are your database host, diaspora database, user and password you created when you set up database for synapse-diaspora-auth
-
-Now follow the steps `given here <https://github.com/kamax-io/mxisd/blob/master/docs/features/authentication.md#advanced>`_. ie, forward the ``/_matrix/client/r0/login`` endpoint to mxisd and add
-
-.. code:: yaml
-
-    dns.overwrite.homeserver.client:
-      - name: '<DOMAIN>'
-        value: 'http://localhost:8008'
-
-where ``<DOMAIN>`` is your matrix server name.
-
-An Apache2 reverse proxy example is already `provided here <https://github.com/kamax-io/mxisd/blob/master/docs/features/authentication.md#apache2>`_. An example nginx configuration would be this:
-
-.. code::
-
-    location /_matrix/client/r0/login {
-        proxy_pass http://localhost:8090/_matrix/client/r0/login;
-        proxy_set_header Host $host;
-        proxy_set_header X-Real-IP $remote_addr;
-        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
-    }
-
-Make sure to put this above other matrix reverse proxy directives. And Congrats! You now have a competely integrated synapse - diaspora setup! :D
