cmd/clef: replace password arg with prompt (#17897)

* cmd/clef: replace password arg with prompt (#17829)

Entering passwords on the command line is not secure as it is easy to recover from bash_history or the process table.
1. The clef command addpw was renamed to setpw to better describe the functionality
2. The <password> argument was removed and replaced with an interactive prompt

* cmd/clef: remove undeclared variable
