Deploy bind-operator and three BIND DNS tiers

Adds the bind-operator and the three BindClusters that replace the
Puppet-managed BIND estate (authoritative / resolver / external-dns).

- add apps/base/bind-system: 9 CRDs, operator Deployment, RBAC (ns bind-system)
- add apps/base/binddns-auth: authoritative BindCluster + catalog zone + TSIG key
- add apps/base/binddns-resolver: recursive-resolver BindCluster with forwarders
- add apps/base/binddns-externaldns: dynamic (RFC2136) BindCluster + TSIG key
- add au-syd1 overlays for all four apps
- register the four apps in the platform ApplicationSet
- add binddns-* namespaces to the platform AppProject destinations
- add schemas/bind.unkin.net/*.json so kubeconform validates the new CRs

DNS Services are LoadBalancer via PureLB. TSIG key material is generated by
the operator into Secrets at runtime (no plain Secrets in git).

properties:
lastTransitionTime:
description: |-
lastTransitionTime is the last time the condition transitioned from one status to another.
This should be when the underlying condition changed. If that is not known, then using the time when the API field changed is acceptable.

observedGeneration represents the .metadata.generation that the condition was set based upon.
For instance, if .metadata.generation is currently 12, but the .status.conditions[x].observedGeneration is 9, the condition is out of date
with respect to the current state of the instance.

reason:
description: |-
reason contains a programmatic identifier indicating the reason for the condition's last transition.
Producers of specific condition types may define expected values and meanings for this field,

The value should be a CamelCase string.
This field may not be empty.
