feat: add new flag to allow configuring per pod FQDNs for service source.
What does it do ?
Currently if you create FQDNs for K8S headless services, a service source will generate DNS record for the source. Also, in addition to that, if pods related to that service has a hostname configured, then FQDNs for each pod will also be created.
I.e. if you have service service-1 resulting into FQDN service-1.some.domain there will also be FQDNs like pod-1.service-1.some.domain be generated.
With this change
Fixes #5937
Motivation
I need to generate per pod FQDNs for pods created by Deployment.

Hi @SerjKol80. Thanks for your PR.
I'm waiting for a github.com member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.
Once the patch is verified, the new status will be reflected by the ok-to-test label.
I understand the commands that are listed here.

What for? There is FQDN support https://github.com/kubernetes-sigs/external-dns/blob/master/docs/advanced/fqdn-templating.md. Is way more flexible

@ivankatliarchuk I'm not sure I got your point. how templating helps me to enable or disable per pods FQDNs for particular service. I.e. today "--source=service" flag will generate tons of DNS records (one per each pod created by StatefulSet). How can I disable it? Or another example: if I want such DNS records for K8s service backed by Deployments' pods. There is no way to do it today. Unless I misunderstood something.
