---------------------------------------------
Okay, the failures were unrelated. I just got two clean test passes. I'll
commit this shortly.
> Logging around core wait for state during startup / recovery is confusing

> I'm seeing some log messages like this:
> I was asked to wait on state recovering for HOST:8984_solr but I still do not
> see the requested state. I see state: recovering live:true
> This is very confusing because from the log, it seems like it's waiting to
> see the state it's in ... After digging through the code, it appears that it
> is really waiting for a leader to become active so that it has a leader to
> recover from.
> I'd like to improve the logging around this critical wait loop to give better
> context to what is happening.
> Also, I would like to change the following so that we force state updates
> every 15 seconds for the entire wait period.
> - if (retry == 15 || retry == 60) {
> + if (retry % 15 == 0) {
> As-is, it's waiting 120 seconds but only forcing the state to update twice,
> once after 15 seconds and again after 60 … might be good to force updates for
> the full wait period.
> Lastly, I think it would be good to use the leaderConflictResolveWait setting
> (from ZkController) here as well since 120 may not be enough for a leader to
> become active in a busy cluster, esp. after the node the Overseer is running
> on. Maybe leaderConflictResolveWait + 5 seconds?
