The login API should not check the password strength

[AlirezaPourchali]

on development environment if you set the admin_pass to something simple, the application starts without a problem but when you try to login you face the following:

{
    "errors": [
        "Field 'Password' failed validation: passwordStrength"
    ],
    "message": "Validation failed",
    "status": "error"
}

I don't think we should check the password strength on a login page, it should be checked when the password is being set.
