In order to perform upgrades the way we would like, it is important that
we avoid any bind mounts into containers. This change ensures that all
system services get their config via stdin.

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

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

This implements existing server-side health checks as defined in
`internal/pkg/cluster/checks` in Talos API.
Summary of changes:
* new `cluster` API
* `apid` now listens without auth on local file socket
* `cluster` API is for now implemented in `machined`, but we can move it
to the new service if we find it more appropriate
* `talosctl health` by default now does server-side health check
UX: `talosctl health` without arguments does health check for the
cluster if it has healthy K8s to return master/worker nodes. If needed,
node list can be overridden with flags.

This merges `osd` API into `machined`. API was copied from `osd` into
`machined`, and `osd` API was deprecated.
For backwards compatibility, `machined` still implements `osd` API, so
older Talos API clients can still talk to the node without changes.
Docs were updated. No functional changes.

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.

This PR will allow users to set the `persist: true` value in their
config data to tell talos not to re-pull the config data at each reboot.
The default will still remain as a "pull every time" methodolgy in order
to encourage immutability by default.

New service `routerd` performs exactly single task: based on incoming
API call service name, it routes the requests to the appropriate Talos
service (`networkd`, `osd`, etc.) Service `routerd` listens of file
socket and routes requests to file sockets.
Service `apid` now does single task as well:
* it either fans out request to other `apid` services running on other
nodes and aggregates responses
* or it forwards requests to local `routerd` (when request destination
is local node)
Cons:
* one more proxying layer on request path
Pros:
* more clear service roles
* `routerd` is part of core Talos, services should register with it to
expose their API; no auth in the service (not exposed to the world)
* `apid` might be replaced with other implementation, it depends on TLS infra,
auth, etc.
* `apid` is better segregated from other Talos services (can only access
`routerd`, can't talk to other Talos services directly, so less exposure
in case of a bug)
This change is no-op to the end users.

This PR brings our protobuf files into conformance with the protobuf

This is to prepare for upcoming switch to reading `/dev/kmsg` which
should allow following logs, doing some kind of tail, etc.
The output is far from being perfect, as `dmesg` data is delivered as
single chunk (not as lines), but once server side updates, client side
should match it.

In `tls.Config`, there are two hooks for getting certificate for client
and server config. So we need separate configuration methods to
configure them both.
Required in apid to provide refreshing TLS client cert to
grpc.ClientConn.

This replaces codegen version of apid proxying with
talos-systems/grpc-proxy based version. Proxying is transparent, it
doesn't require exact information about methods and response types. It
requires some common layout response to enhance it properly with node
metadata or errors.
There should be no signifcant changes to the API with the previous
version, but it's worth mentioning a few changes:
1. grpc.ClientConn is established just once per upstream (either local
service or remote apid instance).
2. When called without `-t` (`targets`), apid proxies immediately down
to local service skipping proxying to itself (as before), which results
in empty node metadata in response (before it had local node IP). Might
revert this later to proxy to itself (?).
3. Streaming APIs are now fully supported with multiple targets, but
message definition doesn't contain `ResponseMetadata`, so streaming APIs
are broken now with targets (needs a fix).
4. Errors are now returned as responses with `Error` field set in
`ResponseMetadata`, this requires client library update and `osctl` to
handle it properly.

Logging is pretty simple and bare minimum is being logged. I believe
better logging can be provided for apid when it does fan-out, but that
is beyond the scope for the first PR.
Sample logs:
```

This installs default middleware to recover from panics (convert them to
errors) in all the grpc servers by default.
Slight refactoring to allow that as grpc can only accept Unary/Stream
interceptors only once.

This brings in the recent updates to protoc-gen-proxy to allow support
for proxying streaming api requests. We artificially limit it to only the first
target specified in the list while we work through what multi target stream
support looks like.

This PR introduces APId. This service replaces the frontend functionality
previously provided by OSD. The main driver for this is two fold:
1. Create a single purpose application to expose the talos api
2. Make use of code generation to DRY api changes
