0.9.1 release of the candig-server.

This release includes a number of enhancements compared to the previous release.

Enhancements:
- Attributes are now properly ingested for the metadata tables, with their Tiers being properly read. This allows individual tables to store data that are not defined in the schemas, with the proper access control retained.
- Improved logicHandler.
- Styling update on dashboard
- Improved documentation, now including sample queries for all clinical, pipeline and complex search endpoints. These sample queries are more tailored to users' need, and would give them a jump-start.
