authz: use `INT[]` to store permissions
Created by: unknwon
Implements using INT[] in addition to roaring bitmap (BYTEA) to store permissions.
- By default, the read path reads from the new format (intarray), and falls back to old format (roaring bitmap) if the new format has empty data.
- Write path writes to tables in both formats.
This is a storage format transition step towards pure-SQL authz approach for more smooth experience for existing customers who are using repository permissions.
