nmcli: connection: process port-type, type and controller first

Browse Source 
If the connection is a port we need to set the connection.port-type
property. Usually this property is guessed by nmcli depending on the
connection type or the chosen controller, so it doesn't need to be
specified by the user. However, if it is explicitly set by the user
we should not guess, but just use it.

When we process arguments like "controller" or "type" we call custom
functions like set_connection_controller that will guess the port-type
if needed. By processing port-type first, it will be set in the
connection by the time that these other properties are processed, so they
won't try to guess.

After port-type, process connection.type and connection.controller, as we
are usually capable of deducing the port-type from them. Type needs to
be processed first because some types like bond-slave or ovs-port have
only one possible port-type value so we must not try to guess from the
controller.
