Slavi Pantaleev c07c927d9f Automatically enable openid listeners when ma1sd enabled
ma1sd requires the openid endpoints for certain functionality.
Example: 90b2b5301c/src/main/java/io/kamax/mxisd/auth/AccountManager.java (L67-L99)

If federation is disabled, we still need to expose these openid APIs on the
federation port.

Previously, we were doing similar magic for Dimension.
As per its documentation, when running unfederated, one is to enable
the openid listener as well. As per their recommendation, people
are advised to do enable it on the Client-Server API port
and use the `federationUrl` variable to override where the federation
port is (making federation requests go to the Client-Server API).

Because ma1sd always uses the federation port (unless you do some
DNS overwriting magic using its configuration -- which we'd rather not
do), it's better if we just default to putting the `openid` listener
where it belongs - on the federation port.

With this commit, we retain the "automatically enable openid APIs" thing
we've been doing for Dimension, but move it to the federation port instead.
We also now do the same thing when ma1sd is enabled.

Controlling Matrix federation (optional)

By default, your server federates with the whole Matrix network. That is, people on your server can communicate with people on any other Matrix server.

Federating only with select servers

To make your server only federate with servers of your choosing, add this to your configuration file (inventory/host_vars/matrix.<your-domain>/vars.yml):

matrix_synapse_federation_domain_whitelist:
- example.com
- another.com

If you wish to disable federation, you can do that with an empty list ([]), or better yet by completely disabling federation (see below).

Exposing the room directory over federation

By default, your server's public rooms directory is not exposed to other servers via federation.

If you wish to expose it, add this to your configuration file (inventory/host_vars/matrix.<your-domain>/vars.yml):

matrix_synapse_allow_public_rooms_over_federation: true

Disabling federation

To completely disable federation, isolating your server from the rest of the Matrix network, add this to your configuration file (inventory/host_vars/matrix.<your-domain>/vars.yml):

matrix_synapse_federation_enabled: false

With that, your server's users will only be able to talk among themselves, but not to anyone who is on another server.

Disabling federation does not necessarily disable the federation port (8448). Services like Dimension and ma1sd normally rely on openid APIs exposed on that port. Even if you disable federation and only if necessary, we may still be exposing the federation port and serving the openid APIs there. To override this and completely disable Synapse's federation port use:

# This stops the federation port on the Synapse side (normally `matrix-synapse:8048` on the container network).
matrix_synapse_federation_port_enabled: false

# This removes the `8448` virtual host from the matrix-nginx-proxy reverse-proxy server.
matrix_nginx_proxy_proxy_matrix_federation_api_enabled: false
