Minimum Password Lenght Ignored and No Limit Set

[LeoNerdoG]

User can set "Minimum password length" to "999999999", which is a pretty big minimum password lenght. I would change this that the maximum value is something similar to 255, as password with 255 characters is more then enoguh long. Also for now this field is totally ignored when updating password.

Testflow:

1. Login to Kura as admin/admin
2. Go to WebConsole Service and change "Minimum password length" to "999999999"
3. Apply changes
4. Try to change password so it contains only couple of characters and try to apply the changes
5. Observe how Kura does not chcek the minimal length of password

Expected behavior "Minimum password length" should not be ignored when creating new password.
