Add options labelFilter and managedRecordTypes in Helm Chart

[abaguas]

Description

By promoting this options to dedicated values they no longer have to be configured via extraArgs.

Motivation

In the K8GB project, a DNS based load balancer, we use external-dns as a chart dependency. We would like to configure all values specific to the controller in the default values of our Chart, and leave to the users the provider configuration. This provider configuration usually includes extraArgs. Since extraArgs is a list that would be overwritten we would like to keep it empty, otherwise users will have to copy paste our base configuration.

Hi @abaguas. Thanks for your PR.

I'm waiting for a kubernetes-sigs 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.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes-sigs/prow repository.
