Add support for custom service selectorLabels

[luarx]

Currently, the service selectors are hardcoded:

{{/*
Selector labels
*/}}
{{- define "haproxy.selectorLabels" -}}
app.kubernetes.io/name: {{ include "haproxy.name" . }}
app.kubernetes.io/instance: {{ .Release.Name }}
{{- end }}

• https://github.com/haproxytech/helm-charts/blob/main/haproxy/templates/_helpers.tpl#L76-L77

The main issue is that when running two HAProxy instances within the same Helm release, they end up sharing the same selectors. As a result, traffic is not routed correctly between the instances.

It would be helpful to have an option to configure additional or custom selectorLabels to better support scenarios like this.
