Breaking change for influxdb receiver

[jpkrohling]

See open-telemetry/opentelemetry-collector-contrib#4277

We need an upgrade routine for v0.31.0 to handle this change. Basically, if this field exists, it has to be removed. Similar to this:

opentelemetry-operator/pkg/collector/upgrade/v0_19_0.go

Lines 47 to 52 in 7250758

	// Remove deprecated queued_retry processor
	if strings.HasPrefix(k.(string), "queued_retry") {
	delete(processors, k)
	otelcol.Status.Messages = append(otelcol.Status.Messages, fmt.Sprintf("upgrade to v0.19.0 removed the processor %q", k))
	continue
	}
