Remove containerd specific parts of the plugin package to prepare its
move out of the main repository. Separate the plugin registration
singleton into a separate package.
Separating out the plugin package and registration makes it easier to
implement external plugins without creating a dependency loop.

Allows containerd.exe to run as a Windows service. eg
Register: `.\containerd.exe --register-service`
Start: `net start containerd`
...
Stop: `net stop containerd`
Unregister: `.\containerd.exe --unregister-service`
When running as a service, logs will go to the Windows application
event log.
The github.com/containerd/containerd/services/server has a lot of
dependencies, like content, snapshots services implementation and
docker-metrics.
For the client side, it uses the config struct from server package
to start up the containerd in background. It will import a lot of
useless packages which might be conflict with existing vendor's package.
It makes integration easier with single config package.
