[Pent Test] reconfigure Ingress manifest according to Pen Test findings

found some issues which can be fixed with Ingres settings

• Cleartext Transmission of Sensitive Information -> set annotation at ingress: nginx.ingress.kubernetes.io/ssl-redirect: "true"
• Information Disclosure – Leakage of Configurational Details -> set annotation at ingress:

    nginx.ingress.kubernetes.io/server-snippet: |
        location /actuator {
          deny all;
          return 403;
        }

• Potentially Denial of Service (DoS) -> should be also fixed with above setting
