Show a password strength meter when using zxcvbn

**Is your feature request related to a problem? Please describe.**
It would be nice to see the password strength visually while typing the new password when using the zxcvbn policy.

**Describe the solution you'd like**
The solution here with the demo would be the best:

and put under the password entry with a thin line.
