In v1 we had a feature called account dormancy which marked users as "dormant" after they had been inactive for 90 days. The mark was automatically removed once the user was seen again, so it did not suspend the user.

This behavior is nearly exactly what's employed by GitHub Enterprise and GitLab, so we should bring it here too.

Automatic Provisioning

Automatic provisioning systems (e.g. SCIM) can create lots of unused user accounts. We want to encourage our customers to use these systems and make it easy for new groups to try Coder. Thus, we should mark these automatically provisioned accounts as dormant until first login.
