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

The gofumports does everything that gofumpt does with the addition of
formatting imports. This change proposes the use of the `-local` flag so
that we can have imports separated in the following order:
- standard library
- third party
- Talos specific

This change aims to make installations more unified and reliable. It
introduces the concept of a mountpoint manager that is capable of
mounting, unmounting, and moving a set of mountpoints in the correct
order.

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.

The responsibility of init should only be to mount the rootfs. This
change moves Talos specific logic into machined. This will allow us to
define a version of Talos in a single binary instead of split across
two. This will enable cleaner upgrades and helps make the codebase
easier to reason about.

This adds generic goroutine runner which simply wraps service as process
goroutine. It supports log redirection and basic panic handling.
DHCP-related part of the network package was slightly adjusted to run as
service with logging updates (to redirect logs to a file) and context
canceling.

This PR introduces dependencies between the services. Now each service
has two virtual events associated with it: 'up' (running and healthy)
and 'down' (finished or failed). These events are used to establish
correct order via conditions abstraction.
Service image unpacking was moved into 'pre' stage simplifying
`init/main.go`, service images are now closer to the code which runs the
service itself.
Step 'pre' now runs after 'wait' step, and service dependencies are now
mixed into other conditions of 'wait' step on startup.

This implements insecure over-file-socket gRPC API for init with two
first simplest APIs: reboot and shutdown (poweroff).
File socket is mounted only to `osd` service, so it is the only service
which can access init API. Osd forwards reboot/shutdown already
implemented APIs to init which actually executes these.
This enables graceful shutdown/reboot with service shutdown, sync, etc.

Most crucial changes in `init/main.go`: on shutdown now Talos tries
to stop gracefully all the services. All the shutdown paths are unified,
including poweroff, reboot and panic handling on startup.
While I was at it, I also fixed bug with containers failing to start
when old snapshot is still around.
Service lifecycle is wrapped with `ServiceRunner` object now which
handles state transitions and captures events related to state changes.
Every change goes to the log as well.
There's no way to capture service state yet, but that is planned to be
implemented as RPC API for `init` which is exposed via `osd` to `osctl`.
Future steps:
1. Implement service dependencies for correct startup order and
shutdown order.
2. Implement service health, so that we can say "start trustd when
containerd is up and healthy".
3. Implement gRPC API for init, expose via osd (service status, restart,
poweroff, ...)
4. Impement 'String()' for conditions, so that we can see what service
is waiting on right now.
