Allow configuring of coredns options

[dionysius]

Is this a BUG REPORT or FEATURE REQUEST?

FEATURE REQUEST

Kubeadm currently only allows definition of mainly crutial options, while coredns has a good list of options to consider allowing to be set. It is difficult to kubectl patch the wished changes to the configmap in afterwards, so requesting the implementation of these/some options. Personally, I'd like to define ttl, resyncperiod, endpoint_pod_names, transfer and ignore empty_service

Versions

kubeadm version (use kubeadm version): current master branch (see link above)

Environment:

• Kubernetes version (use kubectl version): unrelated
• Cloud provider or hardware configuration: unrelated
• OS (e.g. from /etc/os-release): unrelated
• Kernel (e.g. uname -a): unrelated
• Others:

What happened?

I have no options to configure the coredns.

What you expected to happen?

I have at least some options to configure the coredns.

How to reproduce it (as minimally and precisely as possible)?

Can't reproduce, options are missing

Anything else we need to know?

Don't think so
