  ovn: Add logical port 'enabled' state.

This patch adds a new column to the Logical_Port table of the
OVN_Northbound database called 'enabled'.  The purpose is to allow a
port to be administratively enabled or disabled.  It is sometimes
useful to keep a port and its related configuration, but temporarily
disable it, which means no traffic is allowed in or out of the port.

The implementation is fairly non-invasive as it only required minor
changes to the logical pipeline.
