Fixes#3062
There's no user-visible change in this PR.
It carefully separates generated secrets (e.g. certs) from source
secrets from the config (e.g. CAs), so that certs are generated on
config changes which actually affect cert input.
And same way separates etcd and Kubernetes PKI, so if etcd CA got
changed, only etcd certs will be regenerated.
This should have noticeable impact with RSA-based PKI as it reduces
number of times PKI gets generated.

ECDSA keys are smaller which decreases Talos config size, they are more
efficient in terms of key generation, signing, etc., so it makes boot
performance better (and config generation as well).

This moves `pkg/config`, `pkg/client` and `pkg/constants`
under `pkg/machinery` umbrella.
And `pkg/machinery` is published as Go module inside Talos repository.

Package `pkg/crypto` was extracted as `github.com/talos-systems/crypto`
repository and Go module.

This makes `pkg/config` directly importable from other projects.
There should be no functional changes.

This ensures that the generated kubeconfig has a namespace. This fixes
an edge case when a user attempts to use the kubeconfig from within a
pod of a different kubernetes cluster. If the kubeconfig does not have a
namespace, kubectl will use the "in cluster namespace" which is
unexpected, especially if the "in cluster namespace" does not exist in
the target cluster.

This is a rewrite of machined. It addresses some of the limitations and
complexity in the implementation. This introduces the idea of a
controller. A controller is responsible for managing the runtime, the
sequencer, and a new state type introduced in this PR.
A few highlights are:
- no more event bus
- functional approach to tasks (no more types defined for each task)
- the task function definition now offers a lot more context, like
access to raw API requests, the current sequence, a logger, the new
state interface, and the runtime interface.
- no more panics to handle reboots
- additional initialize and reboot sequences
- graceful gRPC server shutdown on critical errors
- config is now stored at install time to avoid having to download it at
install time and at boot time
- upgrades now use the local config instead of downloading it
- the upgrade API's preserve option takes precedence over the config's
install force option
Additionally, this pulls various packes in under machined to make the
code easier to navigate.

Fixes#1906
This provides lifetime as duration relative to kubeconfig generation
time (the moment `osctl kubeconfig` was called).

This extracts admin kubeconfig generation out of bootkube, now based on
Talos x509 library. On each API request for `kubeconfig`, config is
generated on the fly and sent back on the wire.
This fixes two issues:
* any master node can now generate `kubeconfig` (worker nodes can do
that too, but that should probably change in the future)
* after upgrade-and-wipe the disk scenario, `osctl kubeconfig` still
works
