[DOC] Add documentation about TCP/Named Pipes

[eByte23]

When using docker containers on windows link containers with --link

I was getting errors connecting to the linked container, after a loooooooong time i found simple by using 'server=tcp:servername' it works.

This would be very helpful for other people.

Thanks
