New Features

• Added new APIs for async job:
  • Session.create_async_job() to create an AsyncJob instance from a query id.
  • AsyncJob.result() now accepts argument result_type to return the results in different formats.
  • AsyncJob.to_df() returns a DataFrame built from the result of this asynchronous job.
  • AsyncJob.query() returns the SQL text of the executed query.
• DataFrame.agg() and RelationalGroupedDataFrame.agg() now accept variable-length arguments.
• Added parameters lsuffix and rsuffix to DataFram.join() and DataFrame.cross_join() to conveniently rename overlapping columns.
• Added Table.drop_table() so you can drop the temp table after DataFrame.cache_result(). Table is also a context manager so you can use the with statement to drop the cache temp table after use.
• Added Session.use_secondary_roles().
• Added functions first_value() and last_value(). (contributed by @chasleslr)
• Added on as an alias for using_columns and how as an alias for join_type in DataFrame.join().

Bug Fixes

• Fixed a bug in Session.create_dataframe() that raised an error when schema names had special characters.
• Fixed a bug in which options set in Session.read.option() were not passed to DataFrame.copy_into_table() as default values.
• Fixed a bug in which DataFrame.copy_into_table() raises an error when a copy option has single quotes in the value.
