Tested using global-net-plugin-ipc which sets PidHost in config.json.
Plugins might need access to host pid namespace. Add support for that.
Tested using aragunathan/global-net-plugin-ipc which sets "pidhost" in
config.json. Observed using `readlink /proc/self/ns/pid` that plugin and
host have the same ns.

Plugins might need access to host ipc namespace. A good usecase is
a volume plugin running iscsi multipath commands that need access to
host kernel locks.
Tested with a custom plugin (aragunathan/global-net-plugin-full) that's
built with `"ipchost" : true` in config.json. Observed using
`readlink /proc/self/ns/ipc` that plugin and host have the same ns.

This persists the "propagated mount" for plugins outside the main
rootfs. This enables `docker plugin upgrade` to not remove potentially
important data during upgrade rather than forcing plugin authors to hard
code a host path to persist data to.
Also migrates old plugins that have a propagated mount which is in the
rootfs on daemon startup.

This fix adds `--filter capability=[volumedriver|authz]` to `docker plugin ls`.
The related docs has been updated.
An integration test has been added.

* Depending on the host configuration between the docker engine and the remote host we wish to mount using sshfs, a password may be required.
* Confirmed syntax for optional parameter with @vieux
* Verified change works as desired with engine running on Ubuntu host and mounting a volume from a file system on a Mac.

Move plugins to shared distribution stack with images.
Create immutable plugin config that matches schema2 requirements.
Ensure data being pushed is same as pulled/created.
Store distribution artifacts in a blobstore.
Run init layer setup for every plugin start.
Fix breakouts from unsafe file accesses.
Add support for `docker plugin install --alias`
Uses normalized references for default names to avoid collisions when using default hosts/tags.
Some refactoring of the plugin manager to support the change, like removing the singleton manager and adding manager config struct.

Legacy plugins expect host-relative paths (such as for Volume.Mount).
However, a containerized plugin cannot respond with a host-relative
path. Therefore, this commit modifies new volume plugins' paths in Mount
and List to prepend the container's rootfs path.
This introduces a new PropagatedMount field in the Plugin Config.
When it is set for volume plugins, RootfsPropagation is set to rshared
and the path specified by PropagatedMount is bind-mounted with rshared
prior to launching the container. This is so that the daemon code can
access the paths returned by the plugin from the host mount namespace.
