Thomas Eizinger 35017537c7 feat(gateway): allow out-of-order allow_access requests (#6403)
Currently, the gateway requires a strict ordering of first receiving a
`request_connection` message, following by multiple `allow_access`
messages. Additionally, access can be granted as part of the initial
`request_connection` message too.

This isn't an ideal design. Setting up a new connection is infallible,
all we need to do is send our ICE credentials back to the client.
However, untangling that will require a bit more effort.

Starting with #6335, following this strict order on the client is a more
difficult. Whilst we can send them in order, it is harder to maintain
those ordering guarantees across all our systems.

To avoid this, we change the gateway to perform an upsert for its local
ACLs for a client. In case that an `allow_access` call would somehow get
to the gateway earlier, we can simply already create the `Peer` and only
set up the actual connection later.
