Hal is sticking around as a contractor for WME, so we won't really need to remove his access to many things (I don't believe), but we should probably clean up at least a few things which imply him to be a current member of the #security-team.
[] Confirm disablement of all ITS-related accounts (Okta, G Suite, office wiki access, etc.)
[] Confirm transfer of relevant G Suite docs (transferred to @acooper)
[] Remove from security-team@
[] Remove from security@
[] Remove from security.wikimedia.org (gerrit change set, is now k8s deploy)
[] Remove info from [officewiki](https://office.wikimedia.org/w/index.php?diff=351689), secteam, etc.
[] Remove info from [[ https://www.mediawiki.org/wiki/Wikimedia_Security_Team | mediawiki.org secteam ]]
[] Archive user pages on office, wikitech and meta as `{{formerStaff}}`, or former #security-team, or something...
[] Remove access from Asana?
