doc: Make explicit that ovs-vswitchd is the preferred switch.

Many people who are looking for an OpenFlow switch assume that
the only way to do it is using ovs-openflowd.  Sometimes they also

itself and is the preferred method of doing so.

 Open vSwitch uses OpenFlow as its preferred method of remote flow
 table configuration.  This is the simplest method of using it with an

 However, it is also possible to use Open vSwitch as a simple OpenFlow
 switch like that provided by the OpenFlow reference implementation
