Clone Environment with current changes into new environment

A session is created for editing and deploying an environment. When an environment A is attempted to be deployed but if it's currently in deploying status then that deploy attempt is failed, but the changes in environment A in that session can be safely assumed is with genuine interest by a valid user , hence instead of destroying the changes Murano can propose the user if the current session can be created into a new environment and deployed.

This scenario can be extended into having two different users editing the same environment in two different session, Currently which session gets deployed depends upon who deploys it first and other session is discarded irrespective of the changes made.
