Unable to specifying custom labels for the deployable components in production strategy

[primeroz]

Describe the bug
this is essentialy a copy of #629 . in that issue the problem was fixed only for the all-in-one strategy and not for the production one

To Reproduce
Steps to reproduce the behavior:

1. Install jaeger operator
2. create a Jaeger instance in production mode and specify labels for components like query and collector
3. jaeger operator will fail to create the pods with an error like

level=error msg="failed to apply the changes" error="Deployment.apps \"jaeger-collector\" is invalid: spec.template.metadata.labels: Invalid value: map[string]string{\"app\":\"jaeger\", \"app.kubernetes.io/component\":\"collector\", \"app.kubernetes.io/instance\":\"jaeger\", \"app.kubernetes.io/managed-by\":\"jaeger-operator\", \"app.kubernetes.io/name\":\"jaeger-collector\", \"app.kubernetes.io/part-of\":\"jaeger-server\"}: `selector` does not match template `labels`" execution="2021-08-11 08:50:22.135410659 +0000 UTC" instance=jaeger namespace=jaeger-server

Expected behavior
custom labels are added to the deployments and jaeger pods get created
