Is your feature request related to a problem?

• Currently there is no automated way of finding security vulnerabilities in the latest ACK service controller images.

Describe the solution you'd like

• Running periodic jobs to scan the latest controller images and if any security vulnerability is surfacing.
• ACK core team will be informed about security vulnerability through a private communication channel

Describe alternatives you've considered

• TODO: research about managed image scanning from public ecr
• Running scan on image of single controller instead of all

I think this is a great idea, maybe hook Clair into the existing prow process / infrastructure that ACK team uses? Quay uses this for its scanning. Just a thought so the entire wheel doesn't have to be re-invented for this.
