DCB - Document how to use the polling packages and the requisition to configure backups

Documentation should give a brief overview on how to select devices for backup and hot to configure it. In addition it should link to the relevant parts of requisition and poller configuration.

Suggest the following structure for this section:

Location: (new section) Operation>Device Configuration Backup>Enable DCB
