b35490a8ba Make v2/Plugin accesses safe.
v2/Plugin struct had fields that were
- purely used by the manager.
- unsafely exposed without proper locking.
This change fixes this, by moving relevant fields to the manager as well
as making remaining fields as private and providing proper accessors for
them.

27a55fba28 Reorganize plugin package into sub packages.
Split plugin package into `store` and `v2/plugin`. Now the functionality
is clearly delineated:
- Manager: Manages the global state of the plugin sub-system.
- PluginStore: Manages a collection of plugins (in memory and on-disk)
- Plugin: Manages the single plugin unit.

This also facilitates splitting the global PluginManager lock into:
- PluginManager lock to protect global states.
- PluginStore lock to protect store states.
- Plugin lock to protect individual plugin states.

Importing "github.com/docker/docker/plugin/store" will provide access
to plugins and has lesser dependencies when compared to importing the
original monolithic `plugin package`.

dfd9187305 Implement plugin restore after daemon restart
This ensures that:

- The in-memory plugin store is populated with all the plugins
- Plugins which were active before daemon restart are active after.
  This utilizes the liverestore feature when available, otherwise it
  manually starts the plugin.

f37117045c plugins: experimental support for new plugin management
This patch introduces a new experimental engine-level plugin management
with a new API and command line. Plugins can be distributed via a Docker
registry, and their lifecycle is managed by the engine.
This makes plugins a first-class construct.

For more background, have a look at issue #20363.

Documentation is in a separate commit. If you want to understand how the
new plugin system works, you can start by reading the documentation.

Note: backwards compatibility with existing plugins is maintained,
albeit they won't benefit from the advantages of the new system.
