Golang augmented net.Dialer with connection pooling, cached DNS record IP's with round-robin & random access.

Notice: you must use single dialer per host

• New(d net.Dialer, address, port string, cPoolInitial, cPoolMax int) (*Dialer, error)
• Dial(network, address string) (net.Conn, error)
• Close()
• String() string
