Before this patch, when containerd is restarted (due to a crash, or
kill, whatever), the daemon would keep trying to process the event
stream against the old socket handles. This would lead to a CPU spin due
to the error handling when the client can't connect to containerd.
This change makes sure the containerd remote client is updated for all
registered libcontainerd clients.
This is not neccessarily the ideal fix which would likely require a
major refactor, but at least gets things to a working state with a
minimal patch.

The event filter used two separate filter-conditions for
"namespace" and "topic". As a result, both events matching
"topic" and events matching "namespace" were subscribed to,
causing events to be handled both by the "plugin" client, and
"container" client.
This patch rewrites the filter to match only if both namespace
and topic match.
Thanks to Stephen Day for providing the correct filter :)

With the contianerd 1.0 migration we now have strongly typed errors that
we can check for process not found.
We also had some bad error checks looking for `ESRCH` which would only
be returned from `unix.Kill` and never from containerd even though we
were checking containerd responses for it.
Fixes some race conditions around process handling and our error checks
that could lead to errors that propagate up to the user that should not.

The `docker info` code was shelling out to obtain the
version of containerd (using the `--version` flag).
Parsing the output of this version string is error-prone,
and not needed, as the containerd API can return the
version.
This patch adds a `Version()` method to the containerd Client
interface, and uses this to get the containerd version.
