cmd/k8s-operator,k8s-operator,go.{mod,sum}: publish proxy status condition for annotated services (#12463) 
Adds a new TailscaleProxyReady condition type for use in corev1.Service
conditions.

Also switch our CRDs to use metav1.Condition instead of
ConnectorCondition. The Go structs are seralized identically, but it
updates some descriptions and validation rules. Update k8s
controller-tools and controller-runtime deps to fix the documentation
generation for metav1.Condition so that it excludes comments and
TODOs.

Stop expecting the fake client to populate TypeMeta in tests. See
kubernetes-sigs/controller-runtime#2633 for details of the change.

Finally, make some minor improvements to validation for service hostnames.

Fixes #12216

Variable references $(VAR_NAME) are expanded using the previously defined
environment variables in the container and any service environment
variables. If a variable cannot be resolved, the reference in the input
string will be unchanged. Double $$ are reduced to a single $, which
allows for escaping the $(VAR_NAME) syntax: i.e. "$$(VAR_NAME)" will
produce the string literal "$(VAR_NAME)". Escaped references will never
be expanded, regardless of whether the variable exists or not. Defaults
to "".
