Shared trait definitions for common [`comprehensive`] resources
This crate defines traits that are designed to be implemented and exported
by one [`Resource`] and consumed by another, so that the implementor and
consumer do not depend on one another.
The only current trait is [`http_diag::HttpDiagHandler`] for exposing
various diagnostic information on a shared HTTP server.
