Filesystem - Shared Folders

[mrnicegyu11]

The users filesystem in a dynamic sidecar shall be extended by and additional folder called share:

- work/workspace
- work/inputs
- work/outputs
- work/share

Similar to the workspace folder share can be cached on the efs. The folder itself however has some additional properties:

1. It is not tied to a node_id but rather to a project_id and or user_id. It can be mounted into several services concurently (shared).
2. The content itself is stored in S3 in the same way the work folder is.
3. To reduce complexity, we will start with a project wide shared folder. Sharing a study should then work by giving the sharee access to all files.
4. The files are either stored in: s3/project_id/ or s3/user_id/project_id whatever works best.
5. In the long term, users will be able to interact with this part of the filesystem through the file broswer in the project homepage
6. Initilally, this will be made availalbe to selected users to receive early feedback
