People often report and ask about these "failures".
More-so previously, when the `docker kill/rm` output was collected,
but it still happens now when people do `systemctl status
matrix-something` and notice that it says "FAILURE".

Suppressing to avoid further time being wasted on saying "this is
expected".

For an unknown reason prometheus ignored the given "numeric" index and replaced it by 1. This made it not work properly, plus multiple workers of same types were not differentiable. With a "string" index, it works as intended.

* Add support for obtain ECDSA keys

* Replace matrix_ssl_lets_encrypt_use_ecdsa_keys for matrix_ssl_lets_encrypt_key_type

I haven't really traced it (yet), but on some servers, I'm observing
`ansible-playbook ... --tags=start` completing very slowly, waiting
to stop services. I can't reproduce this on all Matrix servers I manage.
I suspect that either the systemd version is to blame or that some
specific service is not responding well to some `docker kill/rm` command.

`ExecStop` seems to work great in all cases and it's what we've been
using for a very long time, so I'm reverting to that.

Seems like Dendrite encourages serving both the Client and Federation
API at the same port.

Coming from Synapse and how things are done there, we have separate
ports. Using separate ports probably makes matrix-corporal (etc.)
integration easier, so separating the APIs by default probably makes
sense.

ExecStopPost should allow us to clean up (docker kill + docker rm)
even if the ExecStart (docker run ..) command failed, and not just after
a graceful service stop was initiated.

We may try to capture such calls and return a friendlier response (HTML
or JSON) saying "The Synapse Admin API is not enabled", but that may not
be desirable.

For now, we stick to what "upstream" recommends: "simply
don't proxy these APIs", which should lead to the same kind of 404 that
we have now.
