Avoid race with udev during ovs agent startup

After taking down the veth link between the physical bridge and the integration
bridge call udevadm settle to wait for any udev events to be completely
processed by the operating system before recreating the veth pair.

Some distributions (e.g. openSUSE) have udev rules installed by default that
call e.g. ifdown <interface> during the remove event. If that is processed
after the ovs agent already brought up the veth pair again the veth pair's
link will be down after the agent completed startup and networking will be
broken for all VM instances.

Reverse the order of interface update and DNAT rule config

Configure DNAT rule first before adding floating ip address to interface
so advanced service router will not receive packets by accident before
DNAT rule configured.

Verified that traffic goes to the VM the created floating ip associated
with right after config.

Fix to enable delete of firewall in PENDING_CREATE state

Firewall will in PENDING_CREATE state if there is no underlying router in the
tenant. When the router and an associated i/f is created then with a sequence
of msgs it is set to ACTIVE state by the plugin. If a delete is triggered when
in PENDING_CREATE state in such a situation, the msg was ignored - fixing this to
account for the fact that a delete makes sense in this situation so the agent
sends the appropriate msg back to the plugin so it can delete it.

Open Icehouse development

This should be accepted/merged once all the RC1 bugfixes are in.

This bumps the target version to 2014.1, effectively opening the master
branch to Icehouse development, ending the feature freeze.
