Add password strength check (#983)

* Add password strength check

* Delete time.sleep and log, use the select class instead

* Ignore W503 in flake8

* Solve some problems of the password strength check algorithm

Part of the code was written by @phisch. This code tries to measure the strength of the user's password and suggests that the password is weak.

* rename function

* Restore the flake8 configuration file to its previous state
