Add way to group exceptions in DependencyTaskGroup

DependencyTaskGroup currently aborts execution if any exceptions are
raised.  This commit provides a way of aggregating all the exceptions
during execution and re-raising them only at the end.

Don't query for resource during stack creation

In Resource.__init__, we unconditionally make a query on the resource
table even if the stack hasn't been stored yet and stack.id is None. The
patch adds a simple conditon to skip it.

Fix comparison with singletons

Many plases in tests code use assertEqual(AA, None),
the same with True and False and negatives of such comparisons.

As comparison to singletons must use `is` operator, appropriate usage
is assertIs, assertIsNot, assertIsNone, assertIsNotNone

These assertions are provided by the `testtools` package,
so this change is not breaking backward compatibility with Python 2.6

This second patch inlcudes the other half of the files touched by these
changes to ease the review.

New middleware to handle SSL termination proxies

The Heat API doesn't behave properly if it is behind an SSL termination
proxy. If this is the case, the HTTP redirections and the links
returned in the REST response bodies are build using http protocol
instead of https.

To handle this situation, a new middleware was added. The purpose of the
SSLMiddleware is to update the wsgi.url_scheme environment variable of
the request with the value contained in an HTTP header that can be
configured in heat.conf (by default: 'X-Forwarded-Proto')

Remove heat-cli-guide

The heat command line clients are documented now better in the
OpenStack End User Guide:

http://docs.openstack.org/user-guide/content/heat-stack-create.html
http://docs.openstack.org/user-guide/content/heat_client_commands.html

The content here is thus not needed anymore, as the README.rst says:
"This documentation should eventually end up in the OpenStack
documentation repositories `api-site` and `openstack-manuals`."

Convert heat_keystoneclient user-create logic to v3 API

Migrate the calls to create the stack user and assign the
stack user role to the v3 API (still using the default domain)

Convert heat_keystoneclient user-delete logic to v3 API

Migrate the delete_stack_user function to use the v3 API.

While making this change, the old retry workaround (which
IIRC was due to a Folsom-era keystone bug) has been removed
as testing indicates it is no longer required.
