nebula-operator non-root image support having issues

Please check the FAQ documentation before raising an issue

Describe the bug (required)

I saw nebula-operator recently merged code change about non-root image support: 1206931,

we saw the following issues:

1. build issues: nebula-operator release-1.8 branch cannot be built successfully as release-1.8 misses this line: https://github.com/vesoft-inc/nebula-operator/blob/master/apis/apps/v1alpha1/nebulacluster_common.go#L30C1-L30C52

2. nabula-agent doesn't support non-root image yet and the functions in this package doesn't work like download files: https://github.com/vesoft-inc/nebula-agent.

Hi
FYI. I’m working on this issue and compatibility of nebula operator and nebula images with OpenShift. Probably I will finish it till the end of this week.
