S3Guard

IMPALA-8344: Add support for running the minicluster with S3Guard
Some tests can fail on S3 due to some operations that are eventually
consistent. S3Guard stores extra metadata in a DynamoDB to solve
several consistency issues.
This adds support for running the minicluster on S3 with S3Guard.
S3Guard is configured by the following environment variables:
S3GUARD_ENABLED: defaults to false, set to true to enable S3Guard
S3GUARD_DYNAMODB_TABLE: name of the DynamoDB table to use. This must
be exclusively owned by this minicluster. The dataload scripts
initialize this table and will purge entries if the table already
exists. The table should be in the same region as the S3_BUCKET
for the minicluster.
S3GUARD_DYNAMODB_REGION - AWS region for S3GUARD_DYNAMODB_TABLE
These environment variables only impact S3 configurations.
The support comes from three pieces:
1. Configuration changes in core-site.xml to add the appropriate
parameters.
2. Updating dataload to initialize/purge the s3guard dynamodb table
and import data appropriately.
3. Update tests to manipulate files through the HDFS command line
rather than through s3 utilities. This takes the filesystem
utility code for ABFS (which actually calls HDFS command line),
makes it generic, and uses it for S3Guard.
Testing:
- Ran multiple rounds of s3 tests
- Aborted tests in the middle and restarted the s3 tests (to test
the s3guard reinitialization code)
