Preview 2

Contains incremental improvements towards the first stable release.

New features:

• Expose stats about scan filters
• Add support for INSERT_IGNORE
• Expose callback for session exceptions

Optimizations and refactors:

• KuduPredicate type validation and performance improvements
• Improve connection shutdown logic
• Add ISecurityContext interface, which allows testing KuduClient without a real server
• Add missing GetBinary(name) overload to RowResult
• Add ToString() to RowResult
• WriteAsync() improvements:
  • Throw an exception on per-row errors (eg. row already exists for inserts, doesn't exist for updates)
  • Return WriteResponse, which contains the raw write timestamp

Bug fixes:

• Prefer tservers in the same location when multiple are local

Misc:

• Add VS Code support
• Update dependencies

Testing:

• Use Knet.Kudu.Binary for integration tests, the .NET port of the kudu-binary jar, https://kudu.apache.org/2019/03/19/testing-apache-kudu-applications-on-the-jvm.html
• Port more tests from the Java client (client stress test, timeout, key encoding)
