Make endpoint_type configurable

Allow to specify the endpoint type to use. Not everybody will
want to use publicURL, so let's make this configurable.

Fix error in RS Auto Scale properties schema

The Rackspace Auto Scale resource's server networks property should be a
list of maps, not a map of strings.  The property description states
that the it is "Networks to attach to", so the property must be a list.

Don't pass empty security groups in port creation

Skip the security_groups argument when the list is empty, as it can
break some neutron extensions not supporting security groups.

Don't delete trust on backup stack delete

Since the trust_id is copied from the stack being backed-up, we
don't want to delete the trust when the backup is deleted, or
the actual stack will break when the next deferred auth operation
occurs.

heat_keystoneclient migrate create_ec2_keypair to v3 API

Convert create_ec2_keypair to use the v3/credentials API, which
is the v3-compatible way to manage ec2 keypairs.

NOTE: requires the fix for keystone bug #1259584 (now in keystone
master) or signature validation with these credentials will fail.

Store credential ID for AccessKey and SignalResponder

These resources create an ec2 keypair, which when managed via the
keystone v3/credentials should be accessed via credential ID not
the access key ID, so store the credential ID for performing any
operations (get/update/delete) on the credential, as it's preferable
to having to do a brute-force lookup by access key (no way to filter
on the access key via v3/credentials)

Assign X-Auth-Url header in a separate middleware

authtoken middleware's current purpose is to set X-Auth-Url header to a
value read from heat.conf.

Since this value is not really related to anything the keystone
middleware does and is instead read from a config file, it makes sense
to move it from the authtoken middleware into its own middleware

This change is the first step to grouping all X-Auth-Url related logic
into one single middleware as opposed to have it scattered (or possibly
repeated) in auth_token and auth_password. For example, auth_password
also has some logic around it related to multi-cloud, which can be
extracted and moved to auth_url middleware in a later patch, so that all
handling of X-Auth-Url occurs in one place.

Also, by extracting the X-Auth-Url logic, it allows cloud
providers to remove auth_token or auth_password without side-effects.

"version" section should be required in template

"HeatTemplateFormatVersion" as default while a template missing version
section now in heat. But then the server can't parse the template in right
way, not translate hot format to cfn. Some errors raised such as:
  Error : At least one Resources member must be defined.
  but "resources" section has one resource.
  Error: The Parameter (image_id) was not defined in template.
  but "image_id" was defined in "parameter" section.

So if we cannot determine the template version, we should raise an
exception. This patch will check whether version section is in template,
if not we should raise exception.

Fix order of arguments in assertEqual (patch 1/2)

Some tests used incorrect order assertEqual(observed, expected).

The correct order expected by testtools is
assertEqual(expected, observed).

This patch includes roughly half of the files touched by these changes
(up to and including test_m* sans contrib code) to ease the review.

Fixed OS::Neutron::Pool creation

Resource OS::Neutron::Pool could not be created when
cookie_name param for session_persistence is not set.

By default params that is not set filled with None
as value and passed to the client. This is incorrent
behaviour in Neutron case. Neutron require that all
fields that is not set should not be passed at all.

So we need to fillter out cookie_name param if it's
value set to None.

Added testr-args option support for tox coverage

So we can check coverage for some test cases like:
