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

We have attribute values we want to match two set of metrics, spans, or logs on, but have a variable part, such as "foo-bar-UUID", where UUID is always different.

Describe the solution you'd like

We want to be able to match 2 sets of signals based on the prefixed, fixed portion of the attribute value, such as "foo-bar".

Describe alternatives you've considered

Right now we wind up doing this:

func shortenNames(value string) string {
	if strings.HasPrefix(value, "kube-proxy") {
		return "kube-proxy"
	}
	if strings.HasPrefix(value, "local-path-provisioner") {
		return "local-path-provisioner"
	}
	if strings.HasPrefix(value, "kindnet") {
		return "kindnet"
	}
	if strings.HasPrefix(value, "coredns") {
		return "coredns"
	}
	if strings.HasPrefix(value, "otelcol") {
		return "otelcol"
	}
	if strings.HasPrefix(value, "sock-splunk-otel-collector-agent") {
		return "sock-splunk-otel-collector-agent"
	}
	if strings.HasPrefix(value, "sock-splunk-otel-collector-k8s-cluster-receiver") {
		return "sock-splunk-otel-collector-k8s-cluster-receiver"
	}
	if strings.HasPrefix(value, "cert-manager-cainjector") {
		return "cert-manager-cainjector"
	}
	if strings.HasPrefix(value, "sock-operator") {
		return "sock-operator"
	}
	if strings.HasPrefix(value, "nodejs-test") {
		return "nodejs-test"
	}
	if strings.HasPrefix(value, "cert-manager-webhook") {
		return "cert-manager-webhook"
	}
	if strings.HasPrefix(value, "cert-manager") {
		return "cert-manager"
	}

	return value
}

and use it here:

pmetrictest.ChangeResourceAttributeValue("k8s.deployment.name", shortenNames),

Sounds like a valid enhancement to me 👍
