                          CachingConnector provides the ability to cache GRPC connections. It provides a GRPC compatible Context Dialer interface via the "DialContext" method. Connections provided by this component are monitored for becoming idle or entering shutdown state. When connections has its usages closed for longer than "idleTime", the connection is closed and removed from the connection cache. Callers must release connections by calling the "ReleaseConn" method. The Close method will flush all remaining open connections. This component should be considered unusable after calling Close.

                          This component has been designed to be safe for concurrency.
