Using RequestUtils to get ints now.
I didn't see that servlets defined via annotation had the loadOnStartup field.
Moving heartbeatScheduler servlet definition to the class rather than in the web.xml to keep things consistent.
Adding javadoc explaining the purpse of the execute endpoint
fixing up the endpoints to use the proper HttpMethods and more consistent naming.
adding stubs for QueueService
Adding add/remove to the job service/repository.
Adding a singleton to the Config class for the JobRepository, but it and the other repos in there need to be dependency  injected into the servlets that need it.
