* Merge #100 from bbeck: Added BoundedExponentialBackoffRetry.
* Merge #102 from artemip: Added REAP_UNTIL_GONE mode to Reaper; Remove items from activePaths once
they are deletes; Tests
* Issue 99: The Double Barrier should allow more than the max to enter the barrier. I don't see any
harm in this.
* Issue 103: Important change/fix for ExhibitorEnsembleProvider: the previous implementation wasn't
handling outages very well. The connectionString could get stuck to an old value if the list of
Exhibitors all went down and couldn't be contacted. Now, a backup provider is required and the backup
is used to update the list of Exhibitors should there be connection problems.
* IMPORTANT NOTE: The 1.0.x branch of Curator is now end of life. There will be a few more releases
but please migrate to the 1.1.x branch.
