mgr/dashboard: Audit REST API calls
Add the ability to auditing REST API calls. This should include all requests that manipulate the configuration/cluster (e.g. PUT/POST/DELETE). It does not make sense to log GET request.
The following features should be included:
- Add config option to enable/disable audit logging
- Add config option to enable/disable the logging of the request payload
Nice to have:
- Add config option to filter what is logged (to reduce number of log messages)
