Console Password Can be One Character Long

[LeoNerdoG]

If user changes default console password from "admin" to something, there is a "Minimum password length" parameter, that specifies how long should the new password be (the default value is "8"). However, this parameter is ignored, as user can create new password with length of total one character.

Testflow:

1. Login to Kura as admin/admin
2. Go to WebConsole service and set new password to "1"
3. Try to save the changes, logout
4. Try to login with the new password - login is successful

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