This add the ability to track the end-to-end performance of ADLS Gen 2 REST APIs by measuring latency in the Hadoop ABFS driver.
The latency information is sent back to the ADLS Gen 2 REST API endpoints in the subsequent requests.

This downgrade the checks for leftover __magic entries from fail to warn now the parallel
test runs make speculation more likely.

This FileSystem instantiation so if an IOException or RuntimeException is
raised in the invocation of FileSystem.initialize() then a best-effort
attempt is made to close the FS instance; exceptions raised that there
are swallowed.
The S3AFileSystem is also modified to do its own cleanup if an
IOException is raised during its initialize() process, it being the
FS we know has the "potential" to leak threads, especially in
extension points (e.g AWS Authenticators) which spawn threads.

in China.

This addresses two scale issues which has surfaced in large scale benchmarks
of the S3A Committers.
* Thread pools are not cleaned up.
This now happens, with tests.
* OOM on job commit for jobs with many thousands of tasks,
each generating tens of (very large) files.
Instead of loading all pending commits into memory as a single list, the list
of files to load is the sole list which is passed around; .pendingset files are
loaded and processed in isolation -and reloaded if necessary for any
abort/rollback operation.
The parallel commit/abort/revert operations now work at the .pendingset level,
rather than that of individual pending commit files. The existing parallelized
Tasks API is still used to commit those files, but with a null thread pool, so
as to serialize the operations.

Replaces the committer-specific terasort and MR test jobs with parameterization
of the (now single tests) and use of file:// over hdfs:// as the cluster FS.
The parameterization ensures that only one of the specific committer tests
run at a time -overloads of the test machines are less likely, and so the
suites can be pulled back into the parallel phase.
There's also more detailed validation of the stage outputs of the terasorting;
if one test fails the rest are all skipped. This and the fact that job
output is stored under target/yarn-${timestamp} means failures should
be more debuggable.

Includes
-S3A glob scans don't bother trying to resolve symlinks
-stack traces don't get lost in getFileStatuses() when exceptions are wrapped
-debug level logging of what is up in Globber
-Contains HADOOP-13373. Add S3A implementation of FSMainOperationsBaseTest.
-ITestRestrictedReadAccess tests incomplete read access to files.
This adds a builder API for constructing globbers which other stores can use
so that they too can skip symlink resolution when not needed.
