Overview of changes
- Support for using Kubernetes style cnames in YugaByte CQL client natively! The sample applications can easily be run as a Kubernetes service now.
- Lots of perf fixes for running YugaByte on machines with large number of CPUs.
- Added built-in time functions such as now(), totimestamp(), tounixtimestamp() and unixtimestampof().
- Support for high-performance batch transaction codepath with intra-batch dependencies.
