Thomas Eizinger 02638582fe feat(connlib): allow controlling IP stack per DNS resource (#9300) ...

With this patch, `connlib` exposes a new, optional field `ip_stack`
within the resource description of each DNS resource that controls the
supported IP stack.

By default, the IP stack is set to `Dual` to preserve the current
behaviour. When set to `IPv4Only` or `IPv6Only`, `connlib` will not
assign any IPv4 or IPv6 addresses when receiving DNS queries for such a
resource. The DNS query will still respond successfully with NOERROR
(and not NXDOMAIN) but the list of IPs will be empty.

This is useful to e.g. allow sys-admins to disable IPv6 for resources
with buggy clients such as the MongoDB atlas driver. The MongoDB driver
does not correctly handle happy-eyeballs and instead fails the
connection early on any connection error.

Additionally, customers operating in IPv6-exclusive networks can disable
IPv4 addresses with this setting.
