IMPALA-7645: Add a query option to set the default table file format
This patch adds a query option "DEFAULT_FILE_FORMAT" to allow setting
the default table file format. Below is the list of supported
"DEFAULT_FILE_FORMAT" query option values:
- TEXT
- RC_FILE
- SEQUENCE_FILE
- AVRO
- PARQUET
- KUDU
- ORC
For backward compatibility, the default table file format remains as
TEXT.
Testing:
- Ran all FE tests
- Added BE test
- Added E2E tests
- Ran test_ddl.py and test_set.py

> It would be useful to have a query option to allow setting the default file
> format. This would allow the file format to be overridden globally or
> per-session. We already have a COMPRESSION_CODEC option.
> We had some discussion on IMPALA-2210 related to this.
> The current default is hardcoded in the code:
