This adds a sentinel error for a missing partition table. This error
is used to detect if a partition table already exists when setting
up user defined disks.
In addition to the fix, this removes a legacy parameter from the
`PartitionTable` method that indicated that the partition table
should be read. It is safer to just read it every time. Also, I
can't think of a case when the block device partition table is nil
and we want to read.

This change ensures that any symlinks under `/dev/disks` are created
by udevd early enough so that users can specify disks identified
by these symlinks in `machine.disks` entries. This change also moves
the udevd-trigger from a service to a post-startup task for udevd.
This is a one time command that doesn't need to be a service. Some
other minor changes were made around parsing the partition name that
makes use of the symlinks created by udevd. This also ensures that
target mount points in `machine.disks` entries are created, fixing a
preexisting bug.

There is no need to really warn about this. We handle this sceanrio just
fine now. The warning just adds confusion.

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.
