This patch adds support for COS(Cloud Object Storage). Using the
hadoop-cos, the implementation is similar to other remote FileSystems.
New flags for COS:
- num_cos_io_threads: Number of COS I/O threads. Defaults to be 16.
Follow-up:
- Support for caching COS file handles will be addressed in
IMPALA-10772.
- test_concurrent_inserts and test_failing_inserts in
test_acid_stress.py are skipped due to slow file listing on
COS (IMPALA-10773).
Tests:
- Upload hdfs test data to a COS bucket. Modify all locations in HMS
DB to point to the COS bucket. Remove some hdfs caching params.
Run CORE tests.

This patch adds support for GCS(Google Cloud Storage). Using the
gcs-connector, the implementation is similar to other remote
FileSystems.
New flags for GCS:
- num_gcs_io_threads: Number of GCS I/O threads. Defaults to be 16.
Follow-up:
- Support for spilling to GCS will be addressed in IMPALA-10561.
- Support for caching GCS file handles will be addressed in
IMPALA-10568.
- test_concurrent_inserts and test_failing_inserts in
test_acid_stress.py are skipped due to slow file listing on
GCS (IMPALA-10562).
- Some tests are skipped due to issues introduced by /etc/hosts setting
on GCE instances (IMPALA-10563).
Tests:
- Compile and create hdfs test data on a GCE instance. Upload test data
to a GCS bucket. Modify all locations in HMS DB to point to the GCS
bucket. Remove some hdfs caching params. Run CORE tests.
- Compile and load snapshot data to a GCS bucket. Run CORE tests.

This removes Impala-lzo from the Impala development environment.
Impala-lzo is not built as part of the Impala build. The LZO plugin
is no longer loaded. LZO tables are not loaded during dataload,
and LZO is no longer tested.
This removes some obsolete scan APIs that were only used by Impala-lzo.
With this commit, Impala-lzo would require code changes to build
against Impala.
The plugin infrastructure is not removed, and this leaves some
LZO support code in place. If someone were to decide to revive
Impala-lzo, they would still be able to load it as a plugin
and get the same functionality as before. This plugin support
may be removed later.
Testing:
- Dryrun of GVO
- Modified TestPartitionMetadataUncompressedTextOnly's
test_unsupported_text_compression() to add LZO case

In CDP build we use Hive3 which has a bug HIVE-22371 (CTAS puts
files in the wrong place). It causes failure of newly added test as
CTAS creates empty table.
Workaround by explicitly creating an external table when hive
version >= 3.
Tested:
Run this test in newest CDP build using job
impala-private-basic-parameterized.

In this patch, we add support for reading zstd encoded text files.
This includes:
1. support reading zstd file written by Hive which uses streaming.
2. support reading zstd file compressed by standard zstd library which
uses block.
To support decompressing both formats, a function ProcessBlockStreaming
is added in zstd decompressor.
Testing done:
Added two backend tests:
1. streaming decompress test.
2. large data test for both block and streaming decompress.
Added two end to end tests:
1. hive and impala integration. For four compression codecs, write in
hive and read from impala.
2. zstd library and impala integration. Copy a zstd lib compressed file
to HDFS, and read from impala.
