add better error handling

[mjhea0]

Add error handlers on both the client in the AJAX requests as well as on the server for failed jobs.

Hi @mjhea0, how can I start on this one?

[mjhea0]

@ibrahimsharaf try thinking of some edge cases, and then add tests. For example, what would happen if the task_type is a string - like hello - rather than an integer? Write a test for this and then add a try/except to the code to get the test to pass.

def create_task(task_type):
    time.sleep(int(task_type) * 10)
    return True
