Add a validation step to parameters schema

This enables validation of of the parameters section of the template, so
that operations like template-validate now return a proper error if
something is wrong.

Modify stack_user_domain config option to take domain ID

It turns out that having the heat service user manipulate (get/create)
domains directly isn't a great idea, because although it works with
the default keystone policy.json, it won't work with the v3cloudsample
policy, which causes some of our tests to fail in the gate when migrating
the User/Access key resources.  Also not allowing the heat user to
create domains is probably more aligned with real deployment policy
expectations.

Note this requires the following devstack change, which will create the
required domain and update heat.conf appropriately:

https://review.openstack.org/#/c/73324/

Or for non-devstack deployments, the domain should be created via
python-openstackclient (which is the only CLI interface to the v3
keystone API, the keystoneclient shell is v2.0 only), e.g:

openstack --os-token <atoken> --os-url=http://<KS_IP>:5000/v3 \
    --os-identity-api-version=3 domain create heat

Add config options to specify stack domain admin

Adds config options to specify a username and password who can
administer the projects & users in the stack domain.  Note this
user must be a domain admin (have admin role in the domain)

Note this requires the following devstack patch:

https://review.openstack.org/#/c/76036/

Or for non-devstack deployments, the domain should be created via
python-openstackclient and heat.conf updated with the username and
password:

openstack --os-token <atoken> --os-url=http://<KS_IP>:5000/v3 \
    --os-identity-api-version=3 user create heat_domain_admin \
    --password <password> --domain <stack_user_domain id>

openstack --os-token <atoken> --os-url=http://<KS_IP>:5000/v3 \
    --os-identity-api-version=3 role add --user heat_domain_admin \
    --password <password> --domain <stack_user_domain id> \
    --domain <stack_user_domain id> admin

engine: allow stack_user_project users to retrieve stack

The current DB scoping (and service.py check) enforces retrieval of
stacks only when they match the request context project/tenant, but
with stack_user_project_id we must make an exception, since these
users will require access to the stack for a subset of operations,
which ones will be enforced via policy.json (not the engine)

migrate StackUser base class to stack domain users

Migrates the user/credential interfaces to stack domain users,
so the user is created in the instance-user domain not the
domain of the user creating the stack.

Implement OS::Neutron::ExtraRoute as /contrib

This codes aims to add support the ExtraRoute resources.

  * Neutron Router ExtraRoute as OS::Neutron::ExtraRoute
  * OS::Neutron::ExtraRoute is implemented in /contrib directory as plugin
  * The resource can be enabled by setting plugin_dirs property in heat.conf
