Update to use the latest Apache incubator version of curator

I am relying upon the tests to ensure correctness. 

- Version 1.3.3 was the last release Netflix made on their own.  See changes here between 1.3.2 and 1.3.3: https://github.com/Netflix/curator/compare/curator-1.3.2...curator-1.3.3
- Version 2.0.0-incubating was the first release under the Apache umbrella
- Version 2.0.1-incubating had very few changes from 2.0.0-incubating and look mostly benign as far as functionality changes go: https://issues.apache.org/jira/secure/ReleaseNote.jspa?projectId=12314425&version=12324348

All in all, none of the changes seem concerning between 1.3.2 and 2.0.1-incubating.
