Implement network creation in compute API

Implements blueprint os-api-network-create

The ability to create new networks is currently only exposed by the
nova-manage CLI. Here we add support for network creation in the
os-networks API extension.

With the exception of num_networks and network_size, all the parameters
supported by 'nova-manage network create' are supported. Only a single
network may be created by each API call.

To avoid code duplication, the nova-manage code is refactored and moved
into NetworkManager so that it can be re-used by the API.

XCP-XAPI version fix

Fixes bug 1033933.

On an Kronos installation (Ubuntu + XCP-XAPI), the reported
software_version dictionary did not contain both product_version and
product_brand. This caused a KeyError. With this fix, the session's
product_version and product_brand will default to None in such cases.
The resize operation's name in these cases will default to VDI.resize.

Add nosehtmloutput as a test dependency.

Adding nosehtmloutput as a test dependency allows nose to output its

Add two prereq pkgs to nova devref env guide

fixes bug 1024903

As noted in the bug report, without libxml2-dev and libxslt-dev
installed on ubuntu 12.04, the virtualenv creation will fail.

This fix simply adds the packages to the first

Ensure log formats are quoted in sample conf

Fixes bug #1040583

This ensures the sample conf has:

  # instance_format="[instance: %(uuid)s] "

rather than:

  # instance_format=[instance: %(uuid)s]

Fix suggested by Vish.

Fix deallocate_fixed_ip() call by unifying signature

deallocate_fixed_ip() is defined in 3 classes with incompatible
signatures:

RPCAllocateFixedIP:
deallocate_fixed_ip(self, context, address, host, **kwargs)
NetworkManager:
deallocate_fixed_ip(self, context, address, **kwargs)
FlatManager:
deallocate_fixed_ip(self, context, address, **kwargs)

There is a non-trivial multiple inheritance relationship among
them. The complication leads to incorrect function call signatures
(see bug 1024789). The kwargs magic is also never used, and discarded
during rpc calls anyway.

This patch makes the call signature exactly the same for all
deallocate_fixed_ip() definitions, drops kwargs and fixes bug
1024789.

Adds integration testing for api samples

We have no validation the the samples at api.openstack.org are
actually correct. This creates a framework to validate the request
and response samples through integration tests.

Adds a bit of stubbing in fake_network to return simple network_info
along with instance records and adds a call in image/fake to get
av valid image.

It will create non-templated versions of the samples when
the tests are running if GENERATE_SAMPLES is set in the environment
when running  nova/tests/integrated/test_api_samples.py

The logic to determine default values for num_networks and network_size
is currently overly convoluted. Simplify it in order to make the intent
more clear, without actually changing the behaviour.
