It's unnecessary and breaks when running from within a docker container:
```
An exception occurred during task execution. To see the full traceback, use -vvv. The error was: TimeoutError: Timer expired after 10 seconds
fatal: [localhost]: FAILED! => {"changed": false, "cmd": "/usr/sbin/udevadm info --query property --name /dev/mapper/vg00-root", "msg": "Timer expired after 10 seconds", "rc": 257}
```
- Creates and defaults an ansible variable for every configuration option in the `kubeproxy.config.k8s.io/v1alpha1` type spec
- Fixes vars that were orphaned by removing non-kubeadm
- Fixes previously harcoded kubeadm values
- Introduces a `main` directory for role default files per component (requires ansible 2.6.0+)
- Split out just `kube-proxy.yml` in this first effort
- Removes the kube-proxy server field patch task
We should continue to pull out other components from `main.yml` into their own defaults files as I did here for `defaults/main/kube-proxy.yml`. I hope for and will need others to join me in this refactoring across the project until each component config template has a matching role defaults file, with shared defaults in `kubespray-defaults` or `downloads`
Migrate older inline= syntax to pure yml syntax for module args as to be consistant with most of the rest of the tasks
Cleanup some spacing in various files
Rename some files named yaml to yml for consistancy
