Validate requests to logSearchApi endpoint (#1375)

- Previously any user with a validate session in console could query the
  `/api/v1/logs/search` endpoint which was not ideal, now we are
  limiting that to users with the `admin:OBDInfo` iam action
- Removing deprecated `has-permission` endpoint and backend code
