Version selection assumes etcd image versions will begin with "v"

[perotinus]

The code that constructs the etcd image version from the CRD spec prefixes the image version with a "v". This assumption breaks in some contexts where the released etcd images from quay.io are not beins used, and it would be useful to have a way to tell the operator to take the image version as-is, without inserting the extra "v" into the versioning scheme.

return fmt.Sprintf("%s:v%v", repo, version)

Looks like #1970 addresses this.
