Expected behaviour

ATLAS has "Clear Server Cache" button on Configuration page. Expected that endpoint is present and it clears all in-memory cache and truncates "cdm_cache" table in application database. Maybe anything else?

Actual behavior

Clicking it request goes to WebAPI/cache/clear endpoint that does not exist. 404 comes as response.
API Documentation does not show the endpoint too: http://webapidoc.ohdsi.org

Steps to reproduce behavior

1. Enable authentication in ATLAS/WebAPI
2. Open Configuration page with "admin" role
3. Click "Clear Server Cache" button
