Review comment:
> With IBR separated in a new thread, maybe later we could have a new
config key that controls IBR interval separately, or add a configurable
constant offset (from the FBR timer) to the IBR timer. This isn't something we
need to add to this jira. Just a thought.
I agree. We can add new config or continue with IBR/FBR expiring around same
time for some time.
