API: Add more search criteria for projects

More search criteria should be proposed to find projects through API.
Ideally we would like to search through all standard and custom properties.

### Current Behavior:

- `/api/v1/project` supports `name` and undocumented `searchText` but it search only through name

REM:
- `/api/v1/search` and `/api/v1/search/project` searches only through name but it is likely ok as this

### Proposed Behavior:

Add additional search properties to `/api/va/project` to tune filer: `group`, `version`, `classifier`, `purl`, `swidTagId`, ...
Also searching through custom properties would be terrific.
