feat(JobQueue Resource) Refs: 29480 (#30303)

### Proposed Changes
This PR includes the integration of the JobQueue implementation with
rest services.
Functionalities such as List, Cancel, Status, Create, and Monitor can be
found here
It also includes two sample JobProcessors to serve as examples and used
be the respective postman tests
