I'm not really sure, but this would probably get tricky - what to do if
user does set host to localhost and connect_type to tcp?

Looking at our code, the connect_type is really not used much:

- if it is set to tcp, the socket is set to empty, what is not
necessary according to http://php.net/mysqli_connect

- if it set to tcp and host is empty error is raised, I'm not sure if
special case here is needed, MySQL will fail as well

- sets server verbose name for socket connection, see https://github.co

Overall I don't think this parameter actually makes sense - so how
about removing it completely?
