IMPALA-7117: Lower debug level for HDFS S3 connector back to INFO

This reverts the changes done in https://gerrit.cloudera.org/#/c/10596/
to set the HDFS S3 connector logs to DEBUG. DEBUG logs drastically increase
the size of the Impala logs during test runs and are no longer necessary
given recent stability improvements to the S3A code and the
Impala-S3Guard integration.
