The primary feature we get with this PR is support for filters and
labels on the image metadata store. In the process of doing this, the
conventions for the API have been converged between containers and
images, providing a model for other services.
With images, `Put` (renamed to `Update` briefly) has been split into a
`Create` and `Update`, allowing one to control the behavior around these
operations. `Update` now includes support for masking fields at the
datastore-level across both the containers and image service. Filters
are now just string values to interpreted directly within the data
store. This should allow for some interesting future use cases in which
the datastore might use the syntax for more efficient query paths.
The containers service has been updated to follow these conventions as
closely as possible.

The implementations for the storage of metadata have been merged into a
single metadata package where they can share storage primitives and
techniques. The is a requisite for the addition of namespaces, which
will require a coordinated layout for records to be organized by
namespace.

For checkpoint into to work you need runc version
639454475cb9c8b861cc599f8bcd5c8c790ae402 + and criu 3.0 as this is what
I have been testing with.

Move restore behind create calls
This remove the restore RPCs in favor of providing the checkpoint
information to the `Create` calls of a container. If provided, the
container will be created/restored from the checkpoint instead of an
existing container.

Server and Client images of the image store are now provided. We have
created an image metadata interface and converted the bolt functions to
implement that interface over an transaction. A remote client
implementation is provided that implements the same interface.

As a demonstration of the power of the visitor implementation, we now
report the image size in the `dist images` command. This is the size of
the packed resources as would be pushed into a remote. A similar method
could be added to calculate the unpacked size.
