If there is no stack found ---> user unable to delete environment "Delete FAILURE"

[Muralikrishnan Ragupathiraju]

Issue:

If there is no stack found -- user unable to delete environment "Delete FAILURE"

Use case:
--------------------
1. Create an Environment and Add Component
2. And then do "Deploy the Environment"
3. Once Deployment was successful ... delete the stack from stack menu "Orchestration--> Stacks-->select the stack--> Delete Stack
4. Now go back to Murano Environment and choose respective environment and delete environment. Now you see the "Delete FAILURE"

Please refer below log and screen shot

    Don't treat stack missing as failure during delete

    If the heat stack has gone by the time an environment tries to delete
    it, issue a warning but don't treat as an error.
