[18.0] [ADD] queue_job_pause: create queue_job_pause module

[JonathanOsAlc]

In some cases, we need to pause only a job since that it is used to schedule a process for a future date but is needed to filter only the paused ones.

Allows to change a channel job to a paused channel (capacity equals zero) using a wizard.
