Azure deployment stack

**Is your feature request related to a problem? Please describe.**
Please add a button to create deployment stacks. To list deployment stacks. To delete deployment stacks. Thank you.

**Describe the solution you'd like**
A clear and concise description of what you want to happen.

The request concerns buttons to create, list, and delete Azure deployment stacks, but it names no files, tests, or entry points. Start by locating the existing deployment-stack and resource-management UI or command paths, then clarify the intended interactions and acceptance criteria for all three operations.
