Description

See HADOOP-18091. S3A auditing leaks memory through ThreadLocal references

• Adds a new option fs.s3a.audit.enabled to controls whether or not auditing
  is enabled. This is false by default.

• When false, the S3A auditing manager is NoopAuditManagerS3A,
  which was formerly only used for unit tests and
  during filsystem initialization.

• When true, ActiveAuditManagerS3A is used for managing auditing,
  allowing auditing events to be reported.

• updates documentation and tests.
