fix(security): patch to tighten security (#6167)

- wrote a patch to enforce a password policy, a default password score
of 2 as calculated by zxcvbn, disallow more than 3 login attempts in a
span of 60 seconds
- added '3' to the allowed password score
- enabled password policy by default
- set 3 as the default value for login attempts in a span of 60 seconds

The motive of this patch is to increase the overall security in frappe framework
Existing passwords won't be affected, however, newly created accounts
will have to adheare to the new password policy guidelines. Once can always
loosen up the security by modifying the values in System Settings, however,
we strongly advice against doing so!
Security is something we take very seriously at frappe,
and hence we chose to make security tighter by default.
