Fix akka logging initialization timeout on startup

Fix akka logging initialization timeout on startup

We've seen CDS internittently failing to startup b/c akka fails to
initialize its logging system - it times out after 5 sec. It seems
on startup threads may be busy enough to prevent akka's message
to inialize the logging actor to timeout. Interestingly, We're only
seeing this on RedHat. The timeout is configured via
logger-startup-timeout which defaults to 5 sec. Increasing it fixes
the issue. I made it really high, 5 min, since if it times out we're
dead in the water anyway.
