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.

Fix two test issues:
- pidof is not available in PATH on some Jenkins systems (rhel, centos)
Use kill -0 instead.
- Cleanup after plugin test. This is a stop gap fix. The right way to
fix this, is to shutdown the plugin on daemon shutdown path (except
for the live-restore case). This will be done in a follow up PR.

This flags enables full support of daemonless containers in docker. It
ensures that docker does not stop containers on shutdown or restore and
properly reconnects to the container when restarted.
This is not the default because of backwards compat but should be the
desired outcome for people running containers in prod.

Fix unmount issues in the daemon crash and restart lifecycle, w.r.t
graph drivers. This change sets a live container RWLayer's activity
count to 1, so that the RWLayer is aware of the mount. Note that
containerd has experimental support for restore live containers.
Added/updated corresponding tests.
