@bavarianbidi there are a couple of comments here:

1. We do need to run conversion-gen and get the updated files.
2. suppose there is a cluster with proxy already set-up using the variables. When they move to the system that you have mentioned, those variables will need to be converted to the new variables above. Those would have to be added to the conversion-gen.

@bavarianbidi We talked about this issue with @arunmk He doesn't want to remove proxy support from VCDCluster spec. I opened a PR, that adds proxy configuration to cloud_init script when only proxy settings are not empty. #395

I think we can close this PR.

close in favor of #395
