Stdlib::Http::Method: Add new type for http methods

This PR creates new new resources:
 * Stdlib::Http::Method for validating http methods
 * Stdlib::Http::Status This is just a copy of Stdlib::Httpstatus
 * make Stdlib::Httpstatus and alias to Stdlib::Http::Status

Ideally we would deprecate Stdlib::Httpstatus in favour of
Stdlib::Http::Status
