Terminates a cluster. Asks for confirmation if debug mode is active or no local keypair matching cluster id can be found.
Local keypairs are deleted, because they are no longer needed after cluster termination.
Keypairs are stored in ~/.config/bibigrid/keys
All servers from all clusters are deleted.
All remote keypairs are deleted.
Application credentials are deleted - if application credentials have been created.
Security Groups are deleted (default and wireguard (if multi-cloud)). BiBiGrid will attempt security group deletion multiple times, because providers need a little time betweens server deletion and security group deletion.
