Job submitter

Allows for easy job management via a REST interface. User is able to start, monitor, get the results and delete running or finished jobs.

Security note! All the methods described below are secured. Authentication requires sending a user proxy certificate (support for SimpleCA signed proxies only) through a request header with the PROXY name and a Base64 encoded proxy as the value.
