display configured kms policies from kes config

Currently the policies are visible only in Raw Edit mode.

Also fix a refresh bug ( once in the tab, just reload the page and the encryption details api is called with undefined for tenant name)

Note: The editing of policy will still be done from Raw Edit mode Tab.

Testing:

have  A running kind cluster with operator/valult deployed 

e.g https://github.com/minio/operator/wiki/Vault,-KES-and-MinIO-Deployed-in-k8s-Cluster

TAG="minio/operator:prakash-test-v3" make all
kind load docker-image docker.io/minio/operator:prakash-test-v3

kubectl kustomize . > operator-test.yaml
# Edit the operator Image  to docker.io/minio/operator:prakash-test-v3
kubectl apply -f operator-test.yaml
#Wait for tenat pods to restart
kubectl minio proxy -n minio-operator

Refresh the tenant and verify that the kms  policies are displayed if available (if not defined it is not displayed)

If there are more policies, they are displayed inside of the scroll able area separated by a line.

how does it look:
