GEODE-8548: Avoid hostname resolution in TcpConn (#659)

- Calling get_host_name() in TcpConn::connect involves a system call that
   might take several seconds to complete.
 - So endpoint is stored instead upon TcpConn construction and used later
   instead of making the system call.
- (pdxcodemonkey) Note that the call in question was buried in use of a LOG* 
macro, which is not best practice

> ACE_Inet_Addr takes too long in reverse DNS resolution

> Whenever TcpConn::connect is called, a system call to *get_host_name* is made 
> in order to obtain reverse resolution for the connection address, right here:
> {code:cpp}
> void TcpConn::connect() {
>   using apache::geode::internal::chrono::duration::to_string;
>   ACE_OS::signal(SIGPIPE, SIG_IGN);  // Ignore broken pipe
>   LOGFINER(std::string("Connecting plain socket stream to ") +
>            inetAddress_.get_host_name() + ":" +
>            std::to_string(inetAddress_.get_port_number()) + " waiting " +
>            to_string(timeout_));
> ยทยทยท
> {code}
> get_host_name executes getnameinfo underlying and the thing is that depending 
> on your system configuration in the case of the address not having a reverse 
> resolution entry it might take a long period. In my case it takes 10 seconds.
