Current implementation of plugin doesn't allow specifying category in the Job, while ideally that's the right place to specify/create category as this will enable users to create category based on job parameters or environment variables.

More background information on this request:
We have complex jenkins architecture and that's why we have recently made all the jobs SVN branch agnostic and they all get SVN branch name as parameter, now there are certain jobs which I don't want to run parallel for each branch for e.g. while trunk is being compiled, it can't compile trunk again but it should be able to compile any other SVN branch.
