Description

This commit will allow for the use of GSS-TSIG updates to an RFC2136 DNS provider. Most commonly, this is implemented by way of "Secure DNS Updates" in Microsoft Active Directory environments.

  • Add in inputs to take in kerberos username/password and whether or not to use gss-tsig for rfc2136 provider
  • Update documentation to outline how to use a kerberos configuration as a configmap for external-dns
  • Use new packages from "github.com/bodgit/tsig/gss" to perform negotiation with kerberos provider for the DNS update using gss-tsig

Fixes #1520

Checklist

  • [ x ] Unit tests updated
  • [ x ] End user documentation updated
