Broke the binding between the discrete IP addresses of the control plane
elements and the ControlPlaneEndpoint. This allows the specification of
a canonical controlplane address which may optionally be a DNS name.

This PR will move to using the external kubeadm v1beta2 structs for our
code base. This will hopefully allow for more stable integrations with
kubeadm in the long term, as well as solve some needs we have in the
machine config rewrite.

Adds handler for specification of additional subjet alt names (SANs) for
the API Server when generating a new cluster configuration using
`osctl`.

This reworks a bunch of the formatting for the userdata generation to
output a cleaner talos config when using IPv6 masters and `osctl config
generate`.
Please note that this changes the scope of concern for master indexing,
keeping `osctl` blissfully unaware of the master-reference chaining.
All it does is report the index of the master it is trying to generate.
The generator itself handles the reference chaining.
Fixes#916, fixes#917, and fixes#918

* refactor(init): Allow kubeadm init on controlplane
This shifts the cluster formation from init(bootstrap) and join(control plane)
to init(control plane).
This makes use of the previously implemented initToken to provide a TTL for
cluster initialization to take place and allows us to mostly treat all control
plane nodes equal. This also sets up the path for us to handle master upgrades
and not be concerned with odd behavior when upgrading the previously defined
init node.
To facilitate kubeadm init across all control plane nodes, we make use of the
initToken to run `kubeadm init phase certs` command to generate any missing
certificates once. All other control plane nodes will attempt to sync the
necessary certs/files via all defined trustd endpoints and being the startup
process.
