Add method CloseIdleConnections for otelhttp.Transport

CloseIdleConnections closes any connections on its Transport which were previously connected from previous requests but are now sitting idle in a "keep-alive" state. It does not interrupt any connections currently in use. If the Client's Transport does not have a CloseIdleConnections method then this method does nothing.
