Title: Workgroup in /etc/samba/smb.conf, error-alert for validation fail of workgroup

- Enables the workgroup change to be reflected in `/etc/samba/smb.conf`.
- Sanitize user input of workgroup `value` for workgroup by stripping the value for whitespaces
- In case of erroneous workgroup `value`, prompt with error message.
