Simulated Job Status Endpoint

A endpoint for testing polling

###Instructions

1. Start the Spring application
2. In a browser, go to http://localhost:9000/job/1
3. The current status of job #1 is dipslayed in the browser, e.g. INPROGRESS
4. Refresh the browser several times until the status changes. Some jobs are stuck in the INPROGRESS and never complete. This is part of the simulation.

How it works

The endpoint's path is /job/{id}, where id can be any string. If the string is unrecognized, a new job is created. If id is recognized, its current status is returned.

The lifecycle of a job is:

                                 +----> COMPLETED
   NOT STARTED +--> IN PROGRESS -|
                                 +----> FAILED

• The lifecycle of a Job is determined randomly by the JobFactory when the Job is created.
• The probability of moving from one state to the next is hardcoded in the JoStateMachine class.
