By default, if a user requests a bind mount it uses private propagation.
When the source path is a path within the daemon root this, along with
some other propagation values that the user can use, causes issues when
the daemon tries to remove a mountpoint because a container will then
have a private reference to that mount which prevents removal.
Unmouting with MNT_DETATCH can help this scenario on newer kernels, but
ultimately this is just covering up the problem and doesn't actually
free up the underlying resources until all references are destroyed.
This change does essentially 2 things:
1. Change the default propagation when unspecified to `rslave` when the
source path is within the daemon root path or a parent of the daemon
root (because everything is using rbinds).
2. Creates a validation error on create when the user tries to specify
an unacceptable propagation mode for these paths...
basically the only two acceptable modes are `rslave` and `rshared`.
In cases where we have used the new default propagation but the
underlying filesystem is not setup to handle it (fs must hvae at least
rshared propagation) instead of erroring out like we normally would,
this falls back to the old default mode of `private`, which preserves
backwards compatibility.

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.

Daemon flags that can be specified multiple times use
singlar names for flags, but plural names for the configuration
file.
To make the daemon configuration know how to correlate
the flag with the corresponding configuration option,
`opt.NewNamedListOptsRef()` should be used instead of
`opt.NewListOptsRef()`.
Commit 6702ac590e6148cb3f606388dde93a011cb14931 attempted
to fix the daemon not corresponding the flag with the configuration
file option, but did so by changing the name of the flag
to plural.
This patch reverts that change, and uses `opt.NewNamedListOptsRef()`
instead.

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 :)

This is a fix to regression in vfs graph driver introduced by
commit 7a1618ced359a3ac92 ("add quota support to VFS graphdriver").
On some filesystems, vfs fails to init with the following error:

> /go/src/github.com/docker/docker/bundles/test-integration/d6bcf6de610e9/root/vfs/backingFsBlockDev:

As quota is not essential for vfs, let's ignore (but log as a warning) any error
from quota init.

Follow the conventions for namespace naming set out by other projects,
such as linuxkit and cri-containerd. Typically, they are some sort of
host name, with a subdomain describing functionality of the namespace.
In the case of linuxkit, services are launched in `services.linuxkit`.
In cri-containerd, pods are launched in `k8s.io`, making it clear that
these are from kubernetes.

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.
