The CreateGroup option in the discovery payload is ignored

According to [the documentation](https://dl.dell.com/topicspdf/dell-openmanage-enterprise_Reference-Guide2_en-us.pdf) page 610 the `CreateGroup` option should create a group on discovery. After testing it, this value seems to be ignored and no group is created.

Start by locating the discovery payload handling and the code that processes the CreateGroup option in this repository. Compare that behavior with the linked Dell OpenManage Enterprise Reference Guide, page 610, then verify completion by confirming that discovery with CreateGroup creates the expected group.
