Is your feature request related to a problem? Please describe.

Hi, I'm running OpenTelemetryCollector with daemonset mode, where all pods are on hostNetwork: true
In my situation, I don't use any service discovery and want to set dnsPolicy: Default, but currently it looks impossible.

opentelemetry-operator/internal/manifests/manifestutils/dns.go

Line 15 in 523e15f

func GetDNSPolicy(hostNetwork bool, dnsConfig corev1.PodDNSConfig) corev1.DNSPolicy {

Describe the solution you'd like

Along with keeping the current logic of setting dnsPolicy, can I add spec.dnsPolicy to the collector attribute?

Describe alternatives you've considered
