Track changes of serviceAccountIssuer in operator status

Description of problem:

This issue exists to drive the backport process of https://github.com/openshift/api/pull/1313

According to the Kubernetes documentation, starting from Kubernetes 1.22, the service-account-issuer flag can be specified multiple times. The first value is then used to generate new tokens and other values are accepted. Using this field can prevent cluster disruptions and allows for smoother reconfiguration of this field.

see: https://kubernetes.io/docs/tasks/configure-pod-container/configure-service-account/#service-account-token-volume-projection

The status field will allow us to keep track of "used" service account issuers and also expire/prune them.

this is a replacement for: #1309
