Removes stale DHCP and L3 namespaces. The cron runs once in 12 hours. Network namespace cleanup is implemented as a daemonset as Kubernetes does not have a cronjob that works like daemonset-cronjob. Network namespace cleanup should run on all nodes where DHCP and L3 agents run. Change-Id: I7525e493067669026e0d57889a3e3238a2bd1308
