WfExS-backend

This is the first release candidate release, and the first one having an official docker image, available at https://github.com/inab/WfExS-backend/pkgs/container/wfexs-backend .

What's Changed

• Docker and Singularity container recipes are considered mature enough.
• Added GitHub CI workflow to automatically generate a docker image on each new tag.
• Added instructions about how to used WfExS-backend in different containerized scenarios (see https://github.com/inab/WfExS-backend/blob/1.0.0rc0/WFEXS-in-CONTAINERS.md).
• Added "disclosable", "cacheable" and "clonable" flags to parameters from the stage definition. These definitions should tell the orchestrator whether the datasets associated to those input parameters contents can be transferred to generated RO-Crates or exported, whether a copy can be kept in the common cache, or whether a copy can be placed in the working directory.
• Now it is allowed to label a dataset cache entry as "clonable" or non "clonable", so it restricts the copies of its contents.
• More publications/posters for the README by @stain in https://github.com/inab/WfExS-backend/pull/112
• Several documentation and small fixes.
