A small tool that will take a list of namespaces and:
Add a TTL annotation to all serviceaccount secrets in them with a value of now + 24h: This will trigger the serviceaccount_secret_refresher controller to delete them as soon as that TTL is in the past
Will update all ServiceAccounts in those namespaces to have empty Secrets and ImagePullSecrets fields: This will trigger an immediate recreation of those secrets by the corresponding minters
