We've moved to using the config, directly. This removes the argument and
gets rid of a few extra lines of code.

Following from the rest of the work in this branch, we now are porting
the dist command to work directly against the containerd content API.

After iterating on the GRPC API, the changes required for the actual
implementation are now included in the content store. The begin change
is the move to a single, atomic `Ingester.Writer` method for locking
content ingestion on a key. From this, comes several new interface
definitions.
The main benefit here is the clarification between `Status` and `Info`
that came out of the GPRC API. `Status` tells the status of a write,
whereas `Info` is for querying metadata about various blobs.

Bring the content service into the containerd API. This allows the
content store to be coordinated in the containerd daemon with minimal
effort. For the most part, this API follows the conventions and behavior
of the existing content store implementation with a few caveats.
Specifically, we remove the object oriented transaction mechanism in
favor of a very rich `Write` call.
Pains are taken to reduce race conditions around when having multiple
writers to a single piece of content. Clients should be able to race
towards getting a write lock on a reference, then wait on each other.
For the most part, this should be generically pluggable to allow
implementations of the content store to be swapped out.
We'll follow this up with an implementation to validate the model.

Updates to the gogo/protobuf dependency are required to correctly

This adds a config file for containerd configuration. It is hard to
have structure data on cli flags and the config file should be used for
the majority of fields when configuring containerd.
There are still a few flags on the daemon that override config file
values but flags should take a back seat going forward and should be
kept at a minimum.

It's duplicate with --log-level, and since --log-level
takes advantage of --debug and it has default value,
--debug never works now.

After reviewing this closer, we removed a few buffers in favor
`(*exec.Command).Output` and simplified the loop file creation method to
just use `(*os.File).Truncate`.
