Few changes required with Upgrade guide

            a. Topic says -> 4.4.5. Checking self-heal schedules
                        Its not a schedule, you can call it as 'status'
            b. I feel we should not say backup of the engine is taken, instead we can call it as 'engine backup is performed along with'
            c.  Section 4.4.2 -> point 1 -> says Edit archive_config.yml, this should be Edit archive_config_inventory.yml
            d. 4.4.2 -> point 3 -> command used , add <host1>, <host2>, <hostt3> which will help user to understand these filies are available in different machines
                           Example:
                         [host1]# scp /root/rhvh-node-<host1name>-backup.tar.gz root.com:/backup/
                         [host2]# scp /root/rhvh-node-<host2name>-backup.tar.gz root.com:/backup/
                         [host3]# scp /root/rhvh-node-<host3name>-backup.tar.gz root.com:/backup/

            e. 4.4.6 , point to RHVM 4.4 repos to be subscribed
            f. 4.4.9 to contain hosted-engine --deploy --restore-from-file=<engine-backup.tar.gz>
            g. Replace ovirt-ansible-hosted-engine-setup with ovirt-ansible-hosted-engine-setup role

Split 4.4.8 in to two sections

 4.4.8 -> Copy the backup files to the newly installed host
 4.4.9 -> Restore gluster configurations on the host


4.4.10 -> point 6 -> Refer to new 4.4.9
