cluster: add significant warning destroying a cluster

[AstroProfundis]

What problem does this PR solve?

Close #1722

What is changed and how it works?

Add a significant warning when the users tries to destroy a cluster. It requires the user to input a long sentence to confirm (instead of a simple "Y/y" letter) so it's highly not possible for the user to destroy a cluster by mistake.
