Upgrade Heat template version from heat_template_version.2015-04-30
to heat_template_version.2018-03-02
The OS::Heat::HARestarter resource type is no longer supported. This resource
type is now hidden from the documentation. HARestarter resources in stacks,
including pre-existing ones, are now only place holders and will no longer do
anything. The recommended alternative is to mark a resource unhealthy and
then do a stack update to replace it. This still correctly manages
dependencies but, unlike HARestarter, also avoid replacing dependent
resources unnecessarily. An example of this technique can be seen in the
auto healing sample templates at
https://git.openstack.org/cgit/openstack/heat-templates/tree/hot/autohealing
The AWS compatible CloudWatch API, deprecated since long has been finally
removed.
With pre-icehouse stacks which contain resources that create users
(such as OS::Nova::Server, OS::Heat::SoftwareDeployment, and OS::Heat::WaitConditionHandle),
it is possible that the users will not be removed upon stack deletion due to
the removal of a legacy fall back code path. In such a situation, these users
will require manual removal.
