This allows to create a client with default values and override those
using functors. As an example, `NewEnvClient()` becomes
`NewClientWithOpts(FromEnv)` ; and if you want a different api version
for this client : `NewClientWithOpts(FromEnv, WithVersion("1.35"))`

Before this change, volume management was relying on the fact that
everything the plugin mounts is visible on the host within the plugin's
rootfs. In practice this caused some issues with mount leaks, so we
changed the behavior such that mounts are not visible on the plugin's
rootfs, but available outside of it, which breaks volume management.
To fix the issue, allow the plugin to scope the path correctly rather
than assuming that everything is visible in `p.Rootfs`.
In practice this is just scoping the `PropagatedMount` paths to the
correct host path.

Setting up the mounts on the host increases chances of mount leakage and
makes for more cleanup after the plugin has stopped.
With this change all mounts for the plugin are performed by the
container runtime and automatically cleaned up when the container exits.

Currently the metrics plugin uses a really hackish host mount with
propagated mounts to get the metrics socket into a plugin after the
plugin is alreay running.
This approach ends up leaking mounts which requires setting the plugin
manager root to private, which causes some other issues.
With this change, plugin subsystems can register a set of modifiers to
apply to the plugin's runtime spec before the plugin is ever started.
This will help to generalize some of the customization work that needs
to happen for various plugin subsystems (and future ones).
Specifically it lets the metrics plugin subsystem append a mount to the
runtime spec to mount the metrics socket in the plugin's mount namespace
rather than the host's and prevetns any leaking due to this mount.

This was added in #36047 just as a way to make sure the tree is fully
unmounted on shutdown.
For ZFS this could be a breaking change since there was no unmount before.
Someone could have setup the zfs tree themselves. It would be better, if
we really do want the cleanup to actually the unpacked layers checking
for mounts rather than a blind recursive unmount of the root.
BTRFS does not use mounts and does not need to unmount anyway.
These was only an unmount to begin with because for some reason the
btrfs tree was being moutned with `private` propagation.
For the other graphdrivers that still have a recursive unmount here...
these were already being unmounted and performing the recursive unmount
shouldn't break anything. If anyone had anything mounted at the
graphdriver location it would have been unmounted on shutdown anyway.

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.

If a blank nodeID was previously passed in it resulted in a node list
request. The response would then fail to umarshal into a `Node`
type returning a JSON error.
This adds an extra validation to all inspect calls to check that the ID

The plugin spec says that plugins can live in one of:
- /var/run/docker/plugins/<name>.sock
- /var/run/docker/plugins/<name>/<name>.sock
- /etc/docker/plugins/<name>.[json,spec]
- /etc/docker/plugins/<name>/<name>.<json,spec>
- /usr/lib/docker/plugins/<name>.<json,spec>
- /usr/lib/docker/plugins/<name>/<name>.<json,spec>
However, the plugin scanner which is used by the volume list API was
doing `filepath.Walk`, which will walk the entire tree for each of the
supported paths.
This means that even v2 plugins in
`/var/run/docker/plugins/<id>/<name>.sock` were being detected as a v1
plugin.
When the v1 plugin loader tried to load such a plugin it would log an
error that it couldn't find it because it doesn't match one of the
supported patterns... e.g. when in a subdir, the subdir name must match
the plugin name for the socket.
There is no behavior change as the error is only on the `Scan()` call,
which is passing names to the plugin registry when someone calls the
volume list API.
