09dc9a2a9e Debugging issue #25511
Volumes and other content created under a bind mount should be
recursively propagated using rshared, not shared. This could be
the reason for EBUSY during removal. Override options with rbind,
rshared and see if CI errors are fixed.

May fix #25511

c04c127ce3 Remove use of exec-root in plugins due to socket pathname limits.
Unix sockets are limited to 108 bytes. As a result, we need to be
careful in not using exec-root as the parent directory for pluginID
(which is already 64 bytes), since it can result in socket path names
longer than 108 bytes. Use /tmp instead. Before this change, setting:
- dockerd --exec-root=/go/src/github.com/do passes
- dockerd --exec-root=/go/src/github.com/doc fails
After this change, there's no failure.

Also, write a volume plugins test to verify that the plugins socket
responds.

9647e4d6cc 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.
