Which chart:
external-dns

Is your feature request related to a problem? Please describe.
Currently we cannot use regex-domain-filter on external-dns chart version 5.1.4. Meanwhile it's already supported on external-dns app version 0.8.0.

• https://github.com/kubernetes-sigs/external-dns/blob/v0.8.0/main.go#L150
• https://github.com/kubernetes-sigs/external-dns/blob/v0.8.0/pkg/apis/externaldns/types.go#L373

Describe the solution you'd like
Please add regex domain filter parameters in the helm chart

regexDomainFilter: "your-regex-pattern"
regexDomainExclusion: "your-regex-pattern"
