- Retry information contains the failure callback, not the retry callback
- All functions take in retry information as an arg instead of its expanded fields
* Rename cb -> callback
* Remove prints
* Fix compiler warnings
* Change some CHECKs to greatest ASSERTs
* Key outstanding callbacks hash table with timer ID instead of callback data pointer
* Use the new retry API for table commands

* Make Plasma tests pass.
* Make Photon tests pass.
* Compile and test with Travis.
* Deactive fetch test so that the tests pass.
