DE170: fix notifications for nova_conf LWRP

nova_conf lwrp currently encapsulates two templates; services should
therefore subscribe the lwrp and not its embedded resources.  for chef
11, `use_inline_resources' is required for this to work (to notify
top-level resources).

(most changes for this are in nova cookbook)

Add fixed_ip_disassociate attributes

Adding attributes for both fixed_ip_disassociate_timeout
and dhcp_lease_time. In nova-network on Folsom, setting
the disassociate timeout also requires modifying the lease
timeout as well, otherwise dnsmasq will disassociate the IP
when the lease expires.
