Review Netdata (official) re docker group gid entry. #515
Description
Post Rockstor v5.5.0-0 we have the gid=-2 directive to run the associated container as the docker group. Apply this, along with the top level description proviso of "Rockstor V5.5.0 or later.".
Rock-on norm changes are currently underway re this Rock-on against #508. Await these changes before attempting this issue.
