[PATCH v2 0/2] stash clear: added safety flag for stash clear subcommand

PLAN: Add a flag to git stash clear (-i|--interactive), which prompts the
user to confirm he indeed wants to clear the stash, otherwise it will abort.

I found it useful as a frequent stash clear user which means my terminal always have it in recent commands, which could mean accidental erase of work. This flag ensures accidental fires won't clear hard work :)

I also thought it would be better to do it opt in, to not change the way the command works in prod, only add to it.

Changes since v1:

Removed temporarily the interactive flag from stash. introduced add-menu lib to the project, which is simply the extracted code that responsible for presenting the menu in the clean command, and made the clean command use it.

This change was made to allow stash to use interactive as well, with the same style as git clean.

Before I continue the development, I would like to know what the community think about this refactor.

Thanks!
