(Updated Jan. 10, 2017, 11:21 p.m.) Review request for Aurora and Santhosh Kumar Shanmugham. Repository: aurora Description ------- WIP for idempotent requests. The changes are basically the following: 1. In the client we construct a thrift transport based on the requests library. A new `TRequestsTransportRetry` adds a http header called `Idempotency-Token`. The retry logic is moved here so that retries will use the same idempotency token. I use the retry library for exponential backoff 2. In the scheduler `TContentAwareServlet` is provided with a `RequestCache` which is nothing but a Guava cache which expires keys after an hour.
