Description of problem: As of today we do not have any section which describes what & why heketi and all its operations in the ocs guides. We need to have this section present in our guides. Basically we need to have the section from [1] to the ocs guides. [1] https://access.redhat.com/documentation/en-us/red_hat_gluster_storage/3.4/html-single/administration_guide/index#idm139715248218224
Make sure the note does also mention that arbiter volumes (besides replica 3) are supported.
I have updated the operation Guide with architecture and introduction part of 5.2 Admin guide Link for verification: https://access.redhat.com/documentation/en-us/red_hat_openshift_container_storage/3.11/html-single/operations_guide/index?lb_target=stage#part-Manage
