In order to enforce strict handling of snapshotter values on the
container object, the defaults have been moved to the client side. This
ensures that we correctly qualify the snapshotter under use when from
the container at the time it was created, rather than possibly losing
the metadata on a change of default.

This fixes a few bugs in the container store related to reading and
writing fields. Specifically, on update, the full field set wasn't being
returned to the caller, making it appear that the store was corrupted.
We now return the correctly updated field and store the missing field
that was omitted in the original implementation. In course, we also have
defined the update semantics of each field, as well as whether or not
they are required.
The big addition here is really the container metadata testsuite. It
covers listing, filtering, creates, updates and deletes in a vareity of
scenarios.

Updates the differ service to support calling and configuring
multiple differs. The differs are configured as an ordered list
of differs which will each be attempting until a supported differ
is called.
Additionally a not supported error type was added to allow differs
to be selective of whether the differ arguments are supported by
the differ. This error type corresponds to the GRPC unimplemented error.

Fixes#1389
This reverts waiting on stdin to finish its IO copy before returning
out.
This was causing `ctr` to block for every container start/exit.

Because we merged the PR that added the API descriptors and modified the
API at the same time. This updates the protobufs to be consistent.

This removes the metric vec that was holding onto all task id and
namespace combinations forever, until containerd was restarted. This
was causing a memory leak with many task.
This also removes the shim cmd where the `Args` is quite large from the
reaper after the shim has been started cutting down on another leak.
This is the first pass through the reaper but more code is required to
fix all the issues when commands are added.

Previously "`/`" in a container was always owned by `root:root` (0/0), even if
`withRemappedSnapshot` had been used. Meaning that if `withUserNamespace` is
used then `/` can be remapped to `nobody:nogroup` (65534/65534).
The fix is is twofold:
- incrementFS should operate on the root of the tree.
- when creating a new snapshot we must propagate the ownership of the topmost
"lower" directory into the new "upper".
