Description of problem: On a setup with more than 1000 volumes, extra parameters are required to be added to the glusterfs daemonset and heketi deployment config as mentioned in this KCS article: https://access.redhat.com/articles/4383621. During upgrade of OCS, due to the recreation of templates, these parameters are lost and has to be added again while creating the new templates. A note should be added to the doc to indicate the same. https://access.redhat.com/documentation/en-us/red_hat_openshift_container_storage/3.11/html-single/deployment_guide/index?lb_target=preview#part-Upgrade
