This allows a plugin to be upgraded without requiring to
uninstall/reinstall a plugin.
Since plugin resources (e.g. volumes) are tied to a plugin ID, this is
important to ensure resources aren't lost.
The plugin must be disabled while upgrading (errors out if enabled).
This does not add any convenience flags for automatically
disabling/re-enabling the plugin during before/after upgrade.
Since an upgrade may change requested permissions, the user is required
to accept permissions just like `docker plugin install`.

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.
