Comment (by pastly):

 dgoulet: can you clarify what message(s) you want to keep and which you
 want to get rid of?

 We have

 `Scheduler type %s has been enabled` every time the scheduler switches
 cleanly. I think we should keep this as notice.

 `Looks like our kernel doesn't have the support for KIST` every time we
 try to use KIST but have to fallback to KISTLite. Should happen at most
 once unless you play games with your torrc and HUPing. I think we should
 keep this as notice (maybe even warn, but we don't want it to be too scary
 since it may not indicate a problem).

 `Scheduler type KIST has been disabled by the consensus or no kernel
 support` which gets called every time we call `select_scheduler()`, have
 KIST in `Schedulers`, but can't use it. I think this should be moved to
 info or removed.

 I will gladly take care of this.
