Make it configurable

First it will select one protocol and try to establish connection up to maxConn type. If it fails all the time then it will switch to next protocol. If all the configured protocols fail to establish a connection then the client will go on hold state. It will wait up to hold time and then it will again try to make a connection using configured protocols.
