Support for old-styled .local Domains (AKS on AzureLocal)

**Title**: Add Support for old-styled .local Domains...

**Description**: Since forcing the normal behavior to ignore .local domain names for mDNS. It can be a charm to build in a switch to override this from out of the box. or by detecting the servers domain name to enforce the use of the "domains-DNS".

Actually it happens only on the control-plane nodes, they are trying to connect to the Cluster / ResourceBridge over the local clustername, ending with the famous .local TLD for example myDomain.local --> myCluster.myDomain.local.

to prevent connection or resolution issues we must set manually on each control-plane node

/etc/systemd/resolved.conf

DNS=`` ``
DOMAIN=~local

after this the dns resolutions is working like expected.

Yes i know that .local TLD is quite old, but in some environments we can't change it in the future.

but if we're able to use a build in mechanism to prevent this, so AzureLocal can be more versatile for more customer-environments
