Optimize hot spots in Stream Manager (#3322) * Replace std::unordered_map with tsl::hopscotch_map in tuple-cache.h * Replaced std::hash with a faster xxhash implementation to speedup the topology if it uses fields-grouping strategy * Enabled O3 optimization level be default to guarantee all smart pointers are inlined * xxhash migration has been rollbacked since its performance effect is negligible * RETRY_ATTEMPTS bumped to 50 since Travis is slow

We recently merged updates to run Heron natively using Mesos in AWS, Mesos/Aurora in AWS, and locally on a laptop.
We also added beta testing for Apache YARN support using Apache REEF, in addition to the Simple Linux Utility for Resource Management (SLURM).
We are working to add support for Mesosphere DC/OS and Kubernetes. We will continue to post updates as we progress.
