[DOP-6713] Add Avro file format support

[dolfinus]

Change Summary

• Added Avro class wrapping options for specific file format.
• Added unit & integration tests.
• Added functions for generating .avro files to generate_files.py, using avro Python package.
• Updated check if Java class is available to use new Connection.get_packages(...) syntax instead of Connection.package.
• Added prohibited options for Avro, ORC and Parquet - they should be passed in Spark session config, not format options. Also wrapped options with frozenset for consistency.
