We were only defining this in `group_vars/matrix_servers`, which is
inconsistent with how we normally do things.

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.

This also disables presence if it's disabled for Synapse.

Similar to 12867e9f18a3321217083, but for `matrix-coturn` (not
`matrix-nginx-proxy`).

We'd like the roles to be self-contained (as much as possible).

Thus, the `matrix-nginx-proxy` shouldn't reference any variables from
other roles. Instead, we rely on injection via
`group_vars/matrix_servers`.

This reverts commit 7d211b71e2.

The multi-arch images are now available, as discussed in #699 (Github Issue).

Fixes #696 (Github Issue)

Regression since 63a49bb2dc.

Related to #685 (Github Issue).

We now automatically expose the APIs when Synapse Admin is enabled.

While v1.22.0 supposedly has multi-arch Docker images
(thanks to https://github.com/matrix-org/synapse/pull/7921),
I can't them on Docker Hub yet, so I'm backing out of this change
for now and letting people fall back to self-building there.

ma1sd 2.4.0 announced experimental support for arm64.
We're making use of those arm64 images instead of self-building.

Fixes #523 (Github Issue).

Related to #529 (Github Issue).

added docs, added seperate service for database, pr comments

We can undo this once https://github.com/ma1uta/ma1sd/issues/44 gets
resolved.

Fixes #494 (Github Issue).

the changes are necessary because certbot images are tagged, so docker does not recognize the necessary architecture

Discussed in #446 (Github Pull Request).
