During OMSAgent for Linux bundle --purge (omi version 1.2.0.35), the omiusers group is not removed. @jeffaco believes this is an OMI issue in postremove.

I'm aware that Ubuntu 16.10 is not currently part of our test matrix, but this is still a small improvement that could be made, allowing OMSAgent for Linux to work cleanly on Ubuntu 16.10.

OMS is not disassociating this group from any OMS users before uninstalling OMI so we failed. This is by design.
