Investigate 110 errors with Terms of Use cerner page

[bosawt]

Last 24 hours: 956 cases of 110 error 1610 cases of non-200 'update_provisioning' calls

• 936 cases of '422' - unprocessable
  • 188 cases of 'cerner provisioned -> false' (and terms accepted -> true) (this would result in 110 error)
• 259 Cases of 499 - client closed the connection (this would result in 110 error)
• 415 cases of '401' - unauthorized (this would result in 110 error) I think this covers most of the 110, there's about 100 left unaccounted for, although these could be accounted by the 422 that are caused by things other than 'cerner provisioned -> false'

• 'client closed the connection' prob can't be helped
• 'cerner provisioned -> false' would be helped by no longer redirecting users who are not cerner eligible through the flow
• '401' - these users come from nowhere, first interaction their IPs have is with update_provisioning. So something is dropping them at the cerner ToU page without being through the auth flow.
