Migrate swagger from /docs to /api/policy/v1/docs

Migrate swagger from /docs to SERVICE_BASE_PATH (/api/policy/v1/docs),

Seems that it is not quite right to have the /docs as it can be confusing for other services, we are exposing services through path, policy service exposed path match api/policy/v1*, following other services convention, therefore, It would make sense to me to have something like api/policy/V1/docs instead, such as for example wellbore or other services
