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 does the following:
- updates the conform config
- cleans up conform scopes
- moves slash commands to the talos-bot
- adds a check list to the pull request template
- disables codecov comments
- uses `BOT_TOKEN` so all actions are performed as the talos-bot user
- adds a `make conformance` target to make it easy for contributors to
check their commit before creating a PR
- bumps golangci-lint to v1.24.0

This fixes cases when large `log.Printf()` was simply lost as it exceeds
max line length (despite being multi-line string with each line below
1KB). Now console logging should be much more reliable.

Fixes#1563
This implements dmesg reading via `/dev/kmsg`, with message parsing and
formatting. Kernel log facility and severity are parsed, timestamp is
calculated relative to boot time (it's accurate unless time jumps a
lot during node lifetime).
New flags to follow dmesg was added, tail flag allows to stream only new
message (ignoring old messages). We could try to implement tailing last
N messages, just a bit more work, open to suggestions (for symmetry with
regular logs).

Since dmesg is not streamed, it becomes difficult to debug issues with
machined. This fixes that by setting up the logging of machine to go to
/dev/kmsg and to a log file.

This removes the github.com/pkg/errors package in favor of the official
error wrapping in go 1.13.

This change aims to standardize the boot process. It introduces the
concept of a phase, which is comprised of tasks. Phases are ran in serial and
the tasks that make up a phase are ran concurrently.
