Co-authored-by: Stepan Mazurov <smazurov@quantummetric.com> ### Motivation In #204, api version of the cert resources was updated to v1. This was insufficient because `v1` has different spec from `v1alpha1` This MR finishes the work that #204 and @lhotari started. ### Modifications Changed the spec of certs to match v1 cert manager spec. ### Verifying this change - [ ] Make sure that the change passes the CI checks.
