[Discussion] distrobox assemble --replace/-R is very risky

Is your feature request related to a problem? Please describe.

I use custom home for my distroboxes. While trying out the distrobox assemble I decided to test the replace option.
I expected it to delete the container, but not the files stored in the custom home. Either way, before running such a destructive operation, it would certainly ask me, .. right? Just like the distrobox rm command I had run manually seconds before.

Nope. No confirmation. distrobox assemble immediately started the cleanup operation, leaving me perplexed about where the confirmation prompt is. Fortunately, I had verbose on and noticed it was already deleting and could Ctrl+C before much damage was done. I still don't know how much data it was able to delete though, if any

Describe the solution you'd like

When running distrobox assemble with --replace/-R or replace=true in distrobox.ini, it should leave the custom home alone or prompt for confirmation if deleting custom home is desired.

We want to replace the container, not nuke associated user data.

P.S : I can help with the code if the recommended behaviour is agreed upon. Wanted to seek your thoughts on this before making changes / sending PR.
