Description of problem:
In order to use the downstream product, the customer needs to provide a "pull secret" also known as entitlement keys in IBM. This is configured during the installation of the Ceph cluster.
When installing IBM Storage Ceph, this results in a pull secret configured for registry cp.icr.io/cp with username cp. The password is a base64 "encrypted" JWT. Inside of this JWT is a key named "jti" which is the JWT ID.
We want to fetch this JWT ID from the ceph config store and send it with the Call Home data in order to try to identify the customer that this cluster belongs to.
