demo: translate to snakemake
Created by: mvidalgarcia
Previous work done for translating the helloworld demo to pure Snakeme was done in this repository: https://github.com/mvidalgarcia/snakemake-playground
The idea behind this issue is to create a reana-snakemake.yaml
pointing to the Snakemake specification (Snakefile).
The load won't work by default as load_workflow_spec
doesn't support snakemake
yet, this will be part of https://github.com/reanahub/reana-client/issues/531.
