KUDU-1563 Support ignore operations in kudu-spark
This patch adds support for the INSERT_IGNORE, UPDATE_IGNORE,
and DELETE_IGNORE operations into the Kudu Spark integration.
It leverages `AsyncKuduClient.supportsIgnoreOperations()` to
handle INSERT_IGNORE operations in a compatible way.

> Add support for INSERT/UPDATE/DELETE IGNORE

> The Java client currently has an [option to ignore duplicate row key errors|
> https://kudu.apache.org/apidocs/org/kududb/client/AsyncKuduSession.html#setIgnoreAllDuplicateRows-boolean-],
> which is implemented by filtering the errors on the client side. If we are
> going to continue to support this feature (and the consensus seems to be that
> we probably should), we should promote it to a first class operation type
> that is handled on the server side. This would have a modest perf.
> improvement since less errors are returned, and it would allow INSERT IGNORE
> ops to be mixed in the same batch as other INSERT, DELETE, UPSERT, etc. ops.
