[FEATURE] Add REST API to trigger a job adhoc

[cwperks]

Is your feature request related to a problem?

Some plugins that utilize the job scheduler, also have the ability to trigger work adhoc. Take for example the reporting plugin that allows a user to define a schedule for producing a report, but also allows the report to triggered adhoc.

I've been thinking about centralizing this logic to the job scheduler by creating a REST API that can trigger a job when called provided the job type and job id. The main benefit of this is that it could be an additional action in the upcoming Dashboards experience for job scheduler that would present a central control plane for actions on scheduled jobs like changing a job's schedule, enabling/disable a job, etc.

What solution would you like?

A new API to trigger a job adhoc.

What alternatives have you considered?

Do nothing

It seems like a good first issue. @cwperks can I work on this?

[cwperks]

@quangdutran absolutely! Sorry I did not see your reply earlier. I will assign this to you. Let me know if you need any code pointers for this one.

Thank you @cwperks

For REST setting, I should take a look at RestGetJobDetailsAction I guess. It should be similar.
The tricky part is how to trigger job run. I think somehow it should be like JobScheduler.reschedule with scheduled job params as immediate run. But it does not look like a service to inject into the RestAction.

Could you give me an advice on how should I go with this API?
