Import the stack module directly

Note: the patch imports "stack as parser" in some places to maintain
API (service.py and event.py).

Use host information passed while starting service

While starting the heat engine service, the host parameter value
being passed to EngineService should be used instead of referring
the conf.
Similarly in the case of EngineListener.

doc: Improve use of the support_status attribute

This patch adds admonitions to the template_guide to indicate support
status of resources to the reader. Deprecated resources will be clearly
indicated, as well as the version in which a resource appeared.

This patch also rework the generated markup to use paragraph nodes
instead of inline nodes inside notes.

Support classes for heat integration tests

These support classes started as a forklift of the classes needed
to run tempest scenario orchestration tests.

The original tempest code has been pared back to provide the
small subset required by heat integration tests. From this point on
these support classes can evolve to the specific needs of the
integration tests.

There is some unused code (especially in remote_client) which has
been left in as it may become useful in the future, and is already
extremely well reviewed and tested from being developed for tempest.

The script heat_integrationtests/generate_sample.sh will generate
an up-to-date heat_integrationtests/heat_integrationtests.conf.sample
file which can be copied to
heat_integrationtests/heat_integrationtests.conf
to override default configuration values. A local ConfigOpts is created
for each test to avoid any potential interaction with heat's
global CONF. Configuration options for credentials default to
being sourced from the environment.

The default tox testenv now excludes tests in heat_integrationtests.
A new testenv called "integration" will only run tests in
heat_integrationtests.

Integration tests will fail if preconditions are not met, including
a keystone endpoint, credentials and glance containing the expected
named image.

Devstack gate hooks have been moved to heat_integrationtests now that
the name of the package has been decided.

Don't evaluate ceilometer watchrules

If you have both Ceilometer and cwlite alarms in one stack (a little odd)
we try to evaluate Ceilometer alarms in the periodic task.

Add tests for list_stacks and count_stacks params

There are no tests for show_deleted and show_nested
params in list_stacks and no test for show_deleted
param in count_stacks. Methods' return depends on
these params, so this patch test correct using of
these params.

Fix cloud-init Python syntax for Python < 2.6

The loguserdata.py file gets uploaded to the servers created by Heat to run
under cloud-init. Since the default versions of Python installed on the
user's server may be very old (e.g. RHEL 5 defaults to Python 2.4), avoid
using the octal syntax introduced for Python 3.0 and backported only as far
as Python 2.6. (Also avoid the old syntax, which will break on Python 3.x.)

Also remove use of the "with" statement from loguserdata.py and
part-handler.py. This statement is only available from Python 2.6 on (or in
Python 2.5 via "from __future__ import with_statement").

Finally, remove use of the "except ExceptionType as value" syntax for
catching exceptions. Again, this was only backported to Python 2.6.
