Do we also want to add a delete method to the backend service or is that redundant?

provider.backend.delete_job(job.job_id())

This PR will conflict with the proposed changes here - https://github.com/Qiskit/qiskit-ibm-provider/pull/338/files#diff-564502a32b289a9dba68e4385287a02dd7e28f86a7f2f9de8603af5408a82dcbR549
So I would like to wait for the other PR to merge before updating and merging this.
