Check PostgreSQL connection count (#2760)
This PR queries PostgreSQL for the `max_connections` and
`superuser_reserved_connections` settings and then ensures that
Dendrite's `max_open_conns` doesn't exceed the allowed value.

This is a really common source of configuration problems and can either
result in blocking queries or deadlocks, so it seems reasonable that we
complain as loudly as possible when it happens.
