echo_middleware_path_auth

middleware for path-based authentication of labstack echo. Best when using apikey for path.

example) https://example.com/api/this_is_api_key

This this_is_api_key part can be dynamically submitted to authentication. For example, whether apikey is active, RateLimit is not exceeded, etc.

Much of this code is based on key_auth.go in labstack/echo and its test code.
