Prevent neutron-l3-agent restart killing metadata service

Browse Source 
The existing handler which prevents keepalived from being killed
during neutron-l3-agent restarts doesn't go far enough at present.

This patch adjusts the processes which are killed to exclude the
haproxy instance which is responsible for proxying the Nova
metadata service.
