feat: enforce strong DB password values

Description

Enforce strong DB password values during clone creation.

The password must have sufficient (60 bits) entropy (raw cryptographic strength of the password). A password with 60 bits of entropy has 2^60 (or about 1.15 quintillion) possible combinations.

This MR doesn't load large datasets, and doesn't contact external services. So, keep in mind that the rules don't protect against common passwords or PWNed passwords.
