[COMMON] Add TLS for Ingress configuration
Instead of setting TLS termination at POD level, it may be interesting
to terminate it at Ingress level.
This patch add the ability to do that using "Ingress" templates.
In order to achieve it, you need to configure it this way in
`values.yaml`:
```yaml
ingress:
enabled: false
service:
- baseaddr: 'my-endpoint'
name: 'my-service'
port: 8080
config:
tls:
secret: my-service-ingress-certs
```
Secret (here `my-service-ingress-certs`) must follow Kubernetest
`kubernetes.io/tls` type: https://kubernetes.io/docs/concepts/services-networking/ingress/#tls
