DNSPolicy scale testing

part of #928

Installation

Adds a new installation overlay namespaced-dns-operator that when applied to a cluster will install multiple instances of the dns operator in different namespaces. Each instance is configured to only watch for dns resources (DNSRecords etc..) in that single namespace.

Templates the kuadrant and dns operator versions in config/install overlays. These should be kept in sync with the branch/tag they are for to allow more easily installing a particular version or latest. These will be automatically updated as part of the release creation.

Testing

Adds a hack/dnspolicy-scale-testing/test.sh script to run multi cluster testing scenarios manually on kind clusters
Adds basic dns testing config for aws,azure,gcp and inmem providers

@maleck13 I added your existing kuadrant install to this task. When we create a release, this will update the kuadrant version to the correct value based on the "VERSION" variable currently set. In the case of main, that will be "latest", but for a semantic version it will be the expected tag e.g. "v1.0.0-rc6"

This is being changed to "latest" because it's on main, this will now get updated to the correct image tag as part of the release process see https://github.com/Kuadrant/kuadrant-operator/pull/1053/files#r1860933307

Installing different versions should be done by checking out the correct version before applying:

git checkout v1.0.0-rc10
kubectl apply -k config/install/standard

or, ideally using a remote ref:

kubectl apply -k github.com/kuadrant/kuadrant-operator/config/install/standard?ref=v1.0.0-rc10
