If we let the hostpath with DirectoryOrCreate to create this directory
it defaults to 0755. A default install should use 0700 for better
security especially if the directory is not present.

'kubeadm reset' uses incorrect way of unmounting /var/lib/kubelet
directories. It queries /proc/mounts for /var/lib/kubelet mount point.
If /var/lib/kubelet directory is also mounted it makes 'kubelet reset'
to unmount it too, which is incorrect. It also makes it fail as it
can't unmount /var/lib/kubelet before unmounting mounts inside it.
Fixed by querying /var/lib/kubelet/ instead of /var/lib/kubelet.
This should exclude /var/lib/kubelet from the query results even if
it's mounted.

As localApiEndpoint is ignored by json.Unmarshaller this should be
localAPIEndpoint as defined in the json tag of the source code.

'kubeadm init' silently ignores --node-name and --cri-socket
command line options if --config option is specified.
Implemented setting 'name' and 'criSocket' options from the command
line even if --config command line option is used.
kubeadm config migrate uses AnyConfigFileAndDefaultsToInternal, which can
unmarshal config from file only if InitConfiguration or JoinConfiguration are
present. Even with that in mind, it can only return a singlie config object,
with InitConfiguration taking precendence over JoinConfiguration. Thus, the
following cases were not handled properly, while they were perfectly valid for
kubeadm init/join:
- ClusterConfiguration only file caused kubeadm config migrate to exit with
error.
- Init + Join configurations in the same file caused Init + Cluster
configuration to be produced (ignoring JoinConfiguration). The same is valid
when the combo is Init + Cluster + Join configurations.
- Cluster + Join configuration ignores ClusterConfiguration and only
JoinConfiguration gets migrated.
To fix this, the following is done:
- Introduce MigrateOldConfigFromFile which migrates old config from a file,
while ensuring that all kubeadm originated input config kinds are taken care
of. Add comprehensive unit tests for this.
- Replace the use of AnyConfigFileAndDefaultsToInternal in
kubeadm config migrate with MigrateOldConfigFromFile.
- Remove the no longer used and error prone AnyConfigFileAndDefaultsToInternal.

'kubeadm join' silently ignores --node-name and --cri-socket
command line options if --config option is specified.
In some cases it's much easier for users to override these parameters
from the command line instead of updating config, especially for
multi-node automatic deployments where only node name should be changed.
Implemented setting 'name' and 'criSocket' options from the command
line even if --config command line option is used.
Bump MinimumControlPlaneVersion and MinimumKubeletVersion to v1.12 and update
any related tests.

Added hostport and host/port parts to the error messages
produced by ParseHostPort API.
This should help users to better identify parsing issues.
