feature: Reject users not approved after N days
Add a --reject-after N
cli option that can be used to trigger
rejection of pending users after N days since user creation. Rejection
is logged on wiki to create a audit log of the bot's actions.
The Procfile entries have been updated to use --reject-after 90
. users
who have been rejected can restart the approval process by logging into
gitlab again.
