Create Job queue to sit in front of the orchestrator

[binarymist]

Current Behaviour:

There is no queue. Currently the Build User has to wait for a Test Run to finish

Proposed Behaviour:

• The queue would sit in front of the orchestrator
• The Build User would no longer have to be conscious about whether the ECS warm-up period was complete (s1 containers were stable), The orchestrator is ready to take orders. (whether or not a Test Run is still in progress) before initiating the test command
• Ability to view Jobs in queue
• Abiltiy to cancel Jobs in queue
• What else?

How It Would Benefit You:

• No more writing code to deal with whether the back-end is ready or not
• Ability to fire and forget Jobs
• What else?
