FIP debug messages

The experimental DVR test job is seeing intermittent failures
related to FIPs.  This patch will add debug log messages to the
l3-agent to help debug the failures.  These logs messages will
indicate when fips have been added and the fip statuses before
they are sent to the plugin.
