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.

Make sure we wait for the client side copy goroutines to start coping
from the fifos before returning from the function.

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".

We were not checking the error value of `Kill` leading to deadlock if the
process didn't exist.

This adds null IO option for efficient handling of IO.
It provides a container directly with `/dev/null` and does not require
any io.Copy within the shim whenever a user does not want the IO of the
container.
