restart keepalived immediately on new vrrp

this is needed because on the first run where multiple of a role type is
detected (eg rabbitmq-server or mysql-master), the vip is pulled from
the environment and used in all the config files.  If keepalived does
not restart until the end of the chef run, services cannot connect to
mysql/rabbit on the configured vip
