Three parts of the code all build up the same SSH shell script snippet for remote tunneling the RPC protocol, but in slightly different ways. Combine them all into one helper method in the virNetClient code, since this logic doesn't really belong in the virNetSocket code. Note that the this change means the shell snippet is passed to the SSH binary as a single arg, instead of three separate args, but this is functionally identical, as the three separate args were combined into one already when passed to the remote system.
