Use system locale when Accept-Language header is not provided

Remove en_US as the default language when no header is provided, and use
None instead. Upon translation None will be defaulted to system as it
was before the translation changes.

Enable GRE and VXLAN with the same ID

Current packet processing in br-tun is based on tun-id,
as a consequence, two networks using different tunnel
types but sharing the same tun-id would not be properly isolated.

To ensure proper isolation within a single bridge, NORMAL action
can't be used any more as it floods unknown unicasts on all
bridges ports. It is replaced by a learn action that dynamically
sets-up flows when packets are recieved from tunnel ports. As mac
address are learnt in explicit flows (in table 20), we can use a
default action in that table to flood unknown unicasts to the
right set of ports, like broadcasts and multicasts packets.

See https://wiki.openstack.org/wiki/Ovs-flow-logic for a more
detailled explanation of the flow logic

Another alternative could have been to use distinct bridges for
each tunnel type (whithout modifying the current flow logic),
but previous alternative may be preferable as it paves the way
for new tunneling optimisations (like RPC based mac learning and
partial-mesh flooding proposed in bp/l2-population)

Fix port creation issue appeared with postgresql backend

IPAllocationPool has relation to IPAvailabilityRange which is setup to
load eagerly. Eager loading is implemented with left outer join which is
incompatible with with_lockmode('update') on postgresql.
The fix redefines eager loading with options(joinedload) making it use
inner join.

Separate l3 db tests for l3 agent into their own test case

Bug 1215871

This patch does a simple refactoring of test_l3_plugin, pushing out tests
aimed at validating the interactions of the l3 agent with the server.

These tests explicitly use TestL3NatPlugin, whereas all the
other tests use a configurable plugin, which might be specificed by a child
class. This might lead to confusion and possibly errors in unit tests for
child classes, especially those not using the l3 agent - for which running
these test is also superfluous.

Avoid performing extra query for fetching mac learning binding

Bug 1214879

Add a relationship performing eager load in the Port model, thus preventing
the 'extend' function from performing an extra query.
This patch also replaces assertTrue with assertEqual in unit tests as it
needs to evaluate whether the value of the mac_learning_enabled attribute
is equal to the boolean literal True, whereas assertTrue verifies that the
expression passed to it evaluates to True. This means that any value but
False will be enough for the test to pass, which is not correct.

Minimize ovs l2 agent calls to get_vif_port_set()

The ovs l2 agent was previously calling get_vif_port_set() on the
integration bridge once per rpc_loop() iteration and then again in
the periodic _report_state() call that returns the current device
count to the neutron service.  Since get_vif_port_set() is an
expensive call (relying on shell commands) and since there
is minimal risk associated with reporting stats that are a few
seconds old, this patch caches the device count for reuse by
_report_state().

Adds support for the Hyper-V WMI V2 namespace

Blueprint: hyper-v-wmi-v2

The Hyper-V APIs are mainly based on WMI. The original 2008 Hyper-V
release introduced the "root\virtualization" namespace which got
superseded in Hyper-V Server / Windows Server 2012 by the
"root\virtualization\v2" namespace (referred as V2 in the sources).

The original namespace has been dropped in the upcoming Hyper-V 2012
R2 (currently available in preview), which means that the Grizzly code
will not be compatible with it as is.

The Hyper-V driver is structured with a clear decoupling between OS
interaction classes (so called *utils modules and classes) and the
agent's logic.

This allows us to provide an implementation of the V2 API without
impacting the rest of the agent's code, based on a factory module
added to instantiate the proper version of the *utils classes: the
original "V1" ones for versions of the OS predating 2012 and the
newer "V2" ones starting from Hyper-V 2012 (Windows kernel version
6.2).
