Add a migration for a security_event_logs table
Created by: flying-robot
The security_event_logs
table houses security-related events, such as
those pertaining to authn/z[0]. It is similar in structure and purpose to
the normal event_logs
table, but without the strict (and short) time
horizon. The migration was extracted from previous work done for 2FA[1].
Any individual actor may have emitted zero, one or many events.
