Returns the ConnectionManager associated with the supplied Connection, creating one on
the first call. Subsequent calls with the same Connection return the cached manager.
Different Connection objects — even for the same username — get distinct managers,
which is the desired behavior: the caller's connection identity is the unit of trust.
