Zach Brown ca78757ca5 scoutfs: more careful client connect timeouts ...

The client connection loop was a bit of a mess.  It only slept between
retries in one particular case.  Other failures to connect would spin
and livelock.  It would spin forever.

This fixed loop now has a much more orderly reconnect procedure.  Each
connecting sender always tries once.  Then retry attempts backoff
exponentially, settling at a nice long timeout.  After long enough it'll
return errors.

This fixes livelocks in the xfstests that mount and unmount around
dm-flakey config.  generic/{034,039,040} would easily livelock before
this fix.
