- Use `schema.TypeMeta` instead of custom `struct` for VK
- More strict check on GVK after `Interpret` in `SplitYAMLDocuments`
- Adjust `Interpret` comment to include JSON
- Add retrieveValidatedConfigInfo to be able to better unit
test the function.
- Break some of the logic in RetrieveValidatedConfigInfo into
helper functions.
- Pass JoinConfiguration.Discovery to RetrieveValidatedConfigInfo
instead of JoinConfiguration.
- Use the discovery timeout per API call to fetch cluster-info
(optionally the user value can be slit in 2).
- Add detailed unit tests for retrieveValidatedConfigInfo.
kubeadm's current implementation of component config support is "kind" centric.
This has its downsides. Namely:
- Kind names and numbers can change between config versions.
Newer kinds can be ignored. Therefore, detection of a version change is
considerably harder.
- A component config can have only one kind that is managed by kubeadm.
Thus a more appropriate way to identify component configs is required.
Probably the best solution identified so far is a config group.
A group name is unlikely to change between versions, while the kind names and
structure can.
Tracking component configs by group name allows us to:
- Spot more easily config version changes and manage alternate versions.
- Support more than one kind in a config group/version.
- Abstract component configs by hiding their exact structure.
Hence, this change rips off the old kind based support for component configs
and replaces it with a group name based one. This also has the following
extra benefits:
- More tests were added.
- kubeadm now errors out if an unsupported version of a known component group
is used.

- Add a new preflight check for upgrade that runs the pause container
with -v in a Job.
- Wait for the Job to complete and return an error after N seconds.
- Manually clean the Job because we don't have the TTL controller
enabled in kubeadm yet (it's still alpha).
Currently this uses the combined kubelet output (stdout + stderr), but this
causes parsing issues if the kubelet logs something on stderr.
Thus we ignore the entire stderr and use stdout only.
We do disable a couple of tests here. That is because the fakeexecer only
supports combined output and return a "not supported" error if `.Output()`
gets invoked thus permanently failing those.

This patch removes pkg/util/mount completely, and replaces it with the
mount package now located at k8s.io/utils/mount. The code found at
k8s.io/utils/mount was moved there from pkg/util/mount, so the code is
identical, just no longer in-tree to k/k.
