Allow for Elasticsearch Virtual service to be created
Had a community-contributor request the possibility to create a virtual service via the .values file similar to how a [kibana-VS](https://repo1.dso.mil/big-bang/product/packages/elasticsearch-kibana/-/blob/main/chart/templates/kibana-vs.yaml?ref_type=heads) is currently deployed
Example:
```
apiVersion: networking.istio.io/v1beta1
kind: VirtualService
metadata:
name: elasticsearch
namespace: logging
spec:
hosts:
- "example.com"
gateways:
- istio-system/public
http:
- route:
- destination:
host: logging-ek-es-http.logging.svc.cluster.local
port:
number: 9200
```
