WIP: This ads the ability to backup results files to an sftp store
Description
Currently benchmarking results are only automatically retained via gitlabs build artifact mechanism, preferably the option should be provided to store results in a more secure way via sftp.
Changes proposed in this merge request:
- Addition of function to store new benchmarking results to a specified sftp store.
- Change to allow build variable to specify storage behavior and necessary parameters to facilitate.
