Thomas Eizinger e901d51550 refactor(gateway): split proxy IP assignment from authorisation (#6812) ...

At the moment, the mapping of proxy IPs to the resolved IPs of a DNS
resource happens at the same time as the "authorisation" that the client
is allowed to talk to that resource. This is somewhat convoluted
because:

- Mapping proxy IPs to resolved IPs only needs to happen for DNS
resources, yet it is called for all resources (and internally skipped).
- Wildcard DNS resources only need to be authorised once, after which
the client is allowed to communicate with any domain matching the
wildcard address.
- The code that models resources within `ClientOnGateway` doesn't
differentiate between resource types at all.

With #6461, the authorisation of a resource will be completely decoupled
from the domain resolution for a particular domain of a DNS resource. To
make that easier to implement, we re-model the internals of
`ClientOnGateway` to differentiate the various resource types. Instead
of holding a single vec of addresses, the IPs are now indexed by the
respective domain. For CIDR resources, we only hold a single address
anyway and for the Internet Resource, the IP networks are static.

This new model now implies that allowing a resource that has already
been allowed essentially implies an update and the filters get
re-calculated.
