add http server root password protection (#757)

- Feature: Added `--security-config-path` option to zenserver to configure security settings
  - Expects a path to a .json file
  - Default is an empty path resulting in no extra security settings and legacy behavior
  - Current support is a top level filter of incoming http requests restricted to the `password` type
  - `password` type will check the `Authorization` header and match it to the selected authorization strategy
  - Currently the security settings is very basic and configured to a fixed username+password at startup
