Change pyrax identity_type of Rackspace resources

The Rackspace resources utilize the pyrax library. As of v1.4.11 of
pyrax, the manner in which default region is determined changed, such
that the keystone identity_type returned 'RegionOne' as the default
region rather than one of the Rackspace regions. Changing the
identity_type to rackspace fixes this.

Handle NetworkNotFoundClient and PortNotFoundClient

neutronclient has changed is behavior (recently?) in that it now
raises PortNotFoundClient for missing ports and NetworkNotFoundClient
for missing nets. These exceptions extend NeutronClientException but
do not set the status_code to 404 so the existing resource 404
checking has stopped working.

This change handles both 404 exceptions and the new exceptions
so that it continues to work with different neutron releases.

Add contrib to tox pep8 check

This implements Clint's comment in
https://review.openstack.org/#/c/48690/1 adding # noqa
to the relative imports and adding contrib to the pep8 check.

Don't obtain resources through stack.resources

A particular logical resource name can be looked up by subscripting the
stack object directly.

Unit tests: don't use status strings from class

We should always obtain the status strings from the object we're actually
using them with. In this test, the parser.Stack class is actually stubbed
out, which can cause problems for accessing its attributes.

Make parser.Stack a proper Mapping

We no longer iterate over things in dependency order, so get rid of the
iterator methods that return values instead of keys. Instead, make
parser.Stack conform to the standard collections.Mapping interface.

Refactor total_resources

Make the implementation slightly faster and more robust:

- Check that res.nested is callable
- Don't call res.nested() more than once
- Check for None explicitly
- Calculate totals directly, rather than with a for loop

Don't iterate over Stack.resources dictionary

Now that parser.Stack is a proper Mapping, we can iterate over its
keys/values/items directly instead of accessing the resources attribute.

Update resource stacks automatically

When moving resources between stacks during an update, update the
