Implement network association in OS API

Networks are associated with projects automatically during launch
of an instance. The network is chosen rather randomly.
This commit adds support for association of given network and project.

DocImpact - when this lands, need to update openstack-manuals repo:
doc/src/docbkx/openstack-api-site/src/wadls/compute-api/src/ext/os-networks.wadl

update python-quantumclient dependency to >=2.0

Nova should depend on a version of quantum client that includes
API v2.0 support.  That means the client version should be 2.0+ .

This was just pushed to PyPi today:

Simple checks for instance user data.

Check that instance user data wont be truncated, and that it is
valid base64 data. This partially resolves bug 1035055. I don't
love the hard coded maximum length, but I haven't worked out how
to get sqlalchemy to tell me the maximum size of the data type.

Return values from wrapped functions in decorators

Calling compute manager methods requires that the decorators
return the value from the underlying function.

This doesn't actually change any return values from methods, because
all existing methods effectively return None.

continue config-drive-v2, add openstack metadata api

This continues the work Michael did on blueprint config-drive-v2

Things added:
 * web service /openstack/2012-08-10 with:
   user_data
   meta_data.json
 * web service supporting /openstack/content

Things changed:
 * Changed the name 'files' (/openstack/files) to be 'content'
   This is to be more generic and apply to future re-use of it
   for some purpose other than personalities (injected_files)
 * 'meta_data.json' and 'user_data' are used for openstack
 * 'user-data' (without .raw) in the ec2 config drive rendering
 * 'content_path' is a attribute of each of the entries in the 'files'
   its value is the path from the openstack metadata service root to
   where the content is located.

   This means that the user does not have to know anything explicit about
   '/content'.  They just have to take the 'content_path' and append it
   to the top level entry point of metadata service.

   Explicit example:
   http://169.254.169.254/openstack/2012-08-10/meta_data.json
   has:
     files[{path: "/etc/passwd", content_path: "/content/0001"}]
   To get the file, user appends 'content_path' to
     http://169.254.169.254/openstack
 * network config (Template) is available in /content also, and
   the key that points to it is 'network_config'. This occurs only
   if there are network's that are "injected" (same behavior as previously)

The meta_data.json now contains
  uuid: <instance uuid>
  meta: meta tags provided they will appear in a dict here
  files:
     This is a list of dicts, where each dict has 2 fields:
       * 'path' (the path provided)
       * 'content_id': the location in /content/ that will give the content
  public-keys:
     Dict of keyname : value
  network_config:
     This is a dict, containing 'content_path' and 'name' (network_config)
  hostname: the hostname
  name: the nova boot name

TODO:
 * want to add other items into openstack metadata
   * public-hostname
   * IP addresses
   * keystone-endpoint
   * url of metadata service: ideally only show this if there
     is a web service available.  the path seems hard coded at the moment
     to be http://169.254.169.254/openstack, but I do not know if there
     is a way to determine if one is present or not.
 * document config-drive-v2

Set task_state=None when finished snapshotting.

Reverts part of recent reverts_task_state commit
d8d7100f8c10ecd388d1943bee9298a913a6990a which removed
code that resets the task_state to None once a snapshot has
been completed.

Added several operators on instance_type_extra_specs.

The following operators on instance_type_extra_specs were added in
compute_capabilities_filter.py:

    = (equal to or greater than as a number; same as vcpus case)
    == (equal to as a number)
    != (not equal to as a number)
    >= (greater than or equal to as a number)
    <= (less than or equal to as a number)
    s== (equal to as a string)
    s!= (not equal to as a string)
    s>= (greater than or equal to as a string)
    s> (greater than as a string)
    s<= (less than or equal to as a string)
    s< (less than as a string)
    <in> (substring)
    <or> (find one of these)

If the first word in the instance_type_extra_spec is not one of the
keywords above, it is ignored.

E.g.: ">= 5", "s== 2.1.0", "<in> gcc", and "<or> fpu <or> gpu"

For more information, please refer:

xenapi: Support live migration without pools

Implement blueprint xenapi-live-block-migration.
Add ability to live migrate VMs to hosts that are not
a part of a host aggregate (block migration).

This requires XenServer 6.1/later, or XCP 1.6/later. As
of this change, we still do not support instances with
(nova/cinder) volumes attached. External kernels are also
not supported.

Remove assigned, but unused variables from nova/db/sqlalchemy/api.py

model_query already create session if it's not supplied in kwargs.
So there was no point in creating session and even not passing it to model_query.
Also, nobody even cares about 'specs' in volume_type_create.
