fixes bug 1047605

This patch adds a periodic resync check to the DHCP agent that will
resync state with the Quantum server if any notification or rpc errors
have occurred since the last check.

Add enable_tunneling openvswitch configuration variable

Not all systems that support Open vSwitch support its GRE tunneling
feature that is not in the Linux kernel source tree. Therefore, a new
configuration variable, enable_tunneling, applies to both the server
and agent. Its default value is False, so it must be set to True to
enable tunneling for tenant and/or provider networks. If
enable_tunneling is False, the server will not allow creation of GRE
networks, and the agent will not initialize the tunnel bridge and will
log an error if there is an attempt to provision a GRE network. If it
is True, the agent now logs an error and exits if it fails to
initialize the patch ports used for the tunnel bridge. Fixes bug
1045610.

When there is an attempt to provision a flat or VLAN network and the
agent has no bridge mapping configured for a the specified physical
network, the agent will now log an error rather than crash.

An undefined variable in a logging statement has been corrected.

Logging levels for openvswitch have been checked and updated where
necessary, and logging statements now avoid the % string substitution
syntax. Fixes bug 1045592.

The corresponding devstack update has already been merged.

Remove an external port when an error occurs during FIP creation.

Fixes bug 1048140

To remove an external port, we need to use the same context used
when it is created.

Ensures that the Linux Bridge Plugin runs with L3 agent

Fixes bug 1048968

1. The external interface for the linux bridge will be created at run time.
The configuration parameter external_network_bridge should be set as empty.
That is, "external_network_bridge = ". The link between the network and
the physical interface should be done via the provider network parameters.
2. The plug operation for the linux bridge replaces the interface name
prefix with tap. We need to ensure that the prefix length is 3 characters.

make subnets attribute of a network read-only

bug 1046173

writing to the subnets attribute is not supported, so rather than
making it looks like we accept it but ignoring it, we should explicitly
reject requests to specify it on network create/update.
