Also remove the comment fields in the vndr script, they are too hard to
keep up to date and add little value when we have the git commit
timestamps

With the rename of fetch to fetch-object, we now introduce the `fetch`
command. It will fetch all of the resources required for an image into
the content store. We'll still need to follow this up with metadata
registration but this is a good start.

To make using the `fetch-object` for demonstrations much easier, the
mediatypes are defaulted when a non-digest object identifier is
provided. We also add support for OCI mediatypes, although they are
mostly unavailable.

To allow us to differentiate from fetching an image, fetch a part of an
image and pulling an image, we now call the `fetch` command the
`fetch-object` command. We can now introduce a command that does the
complete image fetch without creating snapshots, allowing `pull` to
perform the entire process.

The message was defined but the method was returning empty, plumb through the
result from the shim layer.

To make restarting after failed pull less racy, we define `Truncate(size
int64) error` on `content.Writer` for the zero offset. Truncating a
writer will dump any existing data and digest state and start from the
beginning. All subsequent writes will start from the zero offset.
For the service, we support this by defining the behavior for a write
that changes the offset. To keep this narrow, we only support writes out
of order at the offset 0, which causes the writer to dump existing data
and reset the local hash.
This makes restarting failed pulls much smoother when there was a
previously encountered error and the source doesn't support arbitrary
seeks or reads at arbitrary offsets. By allowing this to be done while
holding the write lock on a ref, we can restart the full download
without causing a race condition.
Once we implement seeking on the `io.Reader` returned by the fetcher,
this will be less useful, but it is good to ensure that our protocol
properly supports this use case for when streaming is the only option.

Allow deletion of content over the GRPC interface. For now, we are going
with a model that conducts reference management outside of the content
store, in the metadata store but this design is valid either way.

Two test cases added
- Prepare, Stat on new layer, should return Active layer.
- Prepare & Commit , Stat on new layer, should return Committed layer
