Updated ephemeral plugin, PQ and protobuf...

Implement core of the root jobs plugin with a proper drivers/pipelines
handling mechanism.
Add delayed jobs for the ephemeral plugin.
Remove ResumeAll, Resume, StopAll, Stop. Replaced with Pause/Resume with
a slice of the pipelines.
Other small improvements.
