Public bug reported:

If we have some networks(with dhcp enabled subnets) created, when we want to create a new network 
nodes, and the dhcp-agent hasn't been started before in that node. If we start dhcp-agent,
sometimes the network resource won't be synced in this nodes, no network related ns and dnsmasq
process created. The root cause is the function _report_state and sync_state are almost executed
at the same time, if _report_state executed first, everything is fine, but if sync_state executed
first, no network resource will be allocated.

L3-agent will do report_state before resource sync, so there is no
problem with router resources.
