Pass integer as parameters to make parallelism parameterizable
I tried to use the new feature introduced in V2.1 to use one job multiple times in a workflow. In order to empower this feature even more I tried to use a test pattern job on multiple tests. Some can be optimized by using a certain degree of parallelism others don't. I wasn't able to use the parameter feature for that since you cannot pass integer values through parameters and parallelism requires integer. I also tried to convert the string to an integer which gave me a valid config.yaml but got stuck executing the job.
This makes the feature unusable for me and i can not keep it DRY.
