OS::Mistral::Workflow resource creates a mistral workflow with
a unique name (resource_id). We replace FAILED resources by
default and replace wont work in this case as it will try to
use the same workflow name for the replacement resouce, if the
'name' property is provided.
If the workflow does not exist/deleted using mistral api directly,
it would create a replacement resource, but it would delete the
workflow when cleaning up the old resource. So we would endup
with a replacement resource without any backing workflow.
This adds a new resource attribute ``always_replace_on_check_failed``
and overrides needs_replace_failed() for OS::Mistral::Workflow.
