* Work with new capei provider
* Fix wksctl os to correctly handle file and flux configuration
* switch to marking workload clusters in spec
* Set up machine info pool in wksctl to pass to controller in existinginfra
* Removes the requirement for a wks-controller.yaml
  The wks controller comes from the existinginfra provider.  We no longer
  need it in the repository when creating a cluster.
* inline files in cluster manifest for integration tests
* plumb inline ssh key through PEM file processing
* set version on cluster for apply_test
* Re-enables k8s 1.16 cluster support
* Plumb Context through 'plan' steps
  Doesn't do anything different as yet, but this will be useful for
  tracing, or for cancelling a command.
* point to new version of existinginfra and allow for the new context parameter in CreateSeedNodeSetupPlan
* store correct versions in local repo
* add explicit kubernetes version to multimaster test
* pin c...

We often get "etcdserver: leader changed" responses from kubectl, which
can be ignored.
Rather than special write special code for that one error, just log and
ignore all errors on 'kubectl get nodes'.

renaming it to `wksctl-controller`

Also standardise the import name 'existinginfrav1'

Bump the version to one that has current packages.
Remove all references to upstream repos otherwise yum prefers them.

My home router uses 192.168.0.1 as the gateway and DNS server;
I believe this is a very popular choice.

Move wksctl tests to a range that doesn't cover this address.

The default is 10% free, which is hard to achieve on my laptop.
Set to 100Mi instead.

So we can treat an error on 'kubectl get nodes' as transient, while
still logging that it happened.
