Read Object from k8s API directly instead of cache to avoid getting outdated object

[Daniel-Fan]

issue: https://github.ibm.com/IBMPrivateCloud/roadmap/issues/62214

Context

Once Route keycloak is created by ODLM, and ODLM would revoke Client.Get() request to read the host from Route object. However, the Route object is instantly reconciled by openshift controller after it is created. As a result, Route Object stored in the ODLM's cache is outdated, and ODLM is not able to update it with error the object has been modified; please apply your changes to the latest version and try again

Solution

Use Reader.Get() to always get the object from the cluster
