Creating TXT record with CRD source

You can create and manage TXT records with the help of CRD source
and DNSEndpoint CRD. Currently, this feature is supported by multiple providers including webhook.

In order to start managing TXT records you need to set the --managed-record-types=TXT flag.

external-dns --source crd --provider webhook --managed-record-types=A --managed-record-types=CNAME --managed-record-types=TXT

Targets within the CRD need to be specified according to the RFC 1035 (section 3.3.14). Below is an example of
example.com DNS TXT two records creation.

NOTE Current implementation do not support RFC 6763 (section 6).
