Headless service: retrieve endpoints via Endpoints resource; evaluate spec.publishNotReadyAddresses

This moves `domain_filter.go` to the `endpoint` package to make it
possible to filter and exclude record names in
`plan.filterRecordsForPlan()` so it does not have to be implemented in
every single provider.

Because some providers access `DomainFilter.filters` directly it had to
be exported.

Add option to define minimum TTL for rfc2136 provider

Remove duplicate targets from endpoints for headless services
