[orchestrator]: Take ssh_key_name as user input

### Problem:
The `ssh_key_name` can be useful for debugging and should be a user input rather than a hard-coded value in the state.rs file.

Start by reading state.rs and trace how orchestrator configuration is collected and passed into state. Make ssh_key_name configurable as user input instead of keeping it hard-coded, then verify that the orchestrator uses the supplied value for debugging.
