Fix to job listing without job array information.

Add support for clean_case flag for the zOpt application.

Support for filtering the jobs list by job array ID.

For example to filter for jobs that belong to array ID 100:

`jobs = client.job.list(job_array=100)`

Include support for zOpt

- Bump version of epiccore to support "task_per_device" on JobSpec API
- Update OpenFoam solver to use "task_per_device", this allows more custom task distrubution. For example, to put 9 partitions per socket for the openfoam solver, you can now do the following:


openfoam_job.solver.task_distribution = Distribution.SOCKET
openfoam_job.solver.tasks_per_device = 9

Added meta-data listing for files.
