## Bug Report

#### What did you do?
```
operator-sdk run bundle --install-mode AllNamespaces -n proactive-node-scaling-operator quay.io/$repo/proactive-node-scaling-operator-bundle:latest
I0202 10:50:13.277327   46403 request.go:645] Throttling request took 1.051324502s, request: GET:https://api.control-cluster-raffa.demo.red-chesterfield.com:6443/apis/authentication.k8s.io/v1beta1?timeout=32s
FATA[0010] Failed to run bundle: create catalog: error creating registry pod: error creating registry pod: create registry pod: Pod "-raffaelespazzoli-proactive-node-scaling-operator-bundle-latest" is invalid: metadata.name: Invalid value: "-raffaelespazzoli-proactive-node-scaling-operator-bundle-latest": a DNS-1123 subdomain must consist of lower case alphanumeric characters, '-' or '.', and must start and end with an alphanumeric character (e.g. 'example.com', regex used for validation is '[a-z0-9]([-a-z0-9]*[a-z0-9])?(\.[a-z0-9]([-a-z0-9]*[a-z0-9])?)*') 
```
I never got this error before. The catalog source pod name is clearly wrong: `-raffaelespazzoli-proactive-node-scaling-operator-bundle-latest`, I probably made some mistake somewhere. How is that name generated?

#### What did you expect to see?

Working bundle

#### What did you see instead? Under which circumstances?
