Maintain dataset groups and their settings

[turnerrainer]

AS A Data Analyst I WANT TO have control over different dataset groups and their settings SO THAT I could create group-based verification rules when importing data

Acceptance Criteria

• [ ] #16 can only be applied on dataset groups defined in scope of this issue
• [ ] Datasets consist of pre-defined Data Classes
• [ ] Different models may have different dataset groups

Versioning

• [ ] All confirmed dataset groups are final and changing them would also result in breaking change (upgrade of major version) of it

  E.g. Columns fname, sname, email would be v1.0.0 Columns fname, sname, email, misc within the same dataset group would be v2.0.0 Moving back to fname, sname, email within the same dataset group would be v3.0.0

• [ ] When breaking change takes place (major version is incremented), all previous datasets are deprecated and new dataset has to be added
