`chrs pipeline-file` — manage text-based file representations of _ChRIS_ pipelines from CLI.
This release introduces two new commands:
- `chris pipeline-file add` uploads a file representation of a _ChRIS_ pipeline
- `chrs pipeline-file convert` manipulates file representation of _ChRIS_ pipelines, converting them between supported formats.
Supported pipeline formats: canonical JSON, expanded JSON, YAML ([RFC 2](https://github.com/FNNDSC/CHRIS_docs/blob/master/rfcs/2-pipeline_yaml.adoc)).
