Print a list of dependencies before delete

[ericabrauer]

Subject of the issue

Unable to see list of dependencies when running sceptre delete.

Your environment

• version of sceptre (sceptre --version): 2.4.0
• version of python (python --version): 2.7.16
• which OS/distro: Mac

Steps to reproduce

sceptre delete {path/to/config}

Expected behaviour

Alternative option to have terminal step through list of all resources (based on dependencies) to ask user if they want to delete each resource.

Actual behaviour

Terminal outputs a list of config paths to all resources (based on dependencies) to be deleted and asks if user accepts.

would a dry-run option (issue #1063) be a valid solution for this request?

no reply from report so concluding that this is a duplicate of #1063
