Adds the option fs.s3a.requester.pays.enabled, which, if set to true, allows
the client to access S3 buckets where the requester is billed for the IO.

Follow-on patch to MAPREDUCE-7341, adding ABFS support and tests
* resilient rename
* tests for job commit through the manifest committer.

Multi object delete of size more than 1000 is not supported by S3 and
fails with MalformedXML error. So implementing paging of requests to
reduce the number of keys in a single request. Page size can be configured
using "fs.s3a.bulk.delete.page.size"

Adds a new map type WeakReferenceMap, which stores weak
references to values, and a WeakReferenceThreadMap subclass
to more closely resemble a thread local type, as it is a
map of threadId to value.
Construct it with a factory method and optional callback
for notification on loss and regeneration.
WeakReferenceThreadMap<WrappingAuditSpan> activeSpan =
new WeakReferenceThreadMap<>(
(k) -> getUnbondedSpan(),
this::noteSpanReferenceLost);
This is used in ActiveAuditManagerS3A for span tracking.
Relates to
* HADOOP-17511. Add an Audit plugin point for S3A
* HADOOP-18094. Disable S3A auditing by default.

Part of HADOOP-17198. Support S3 Access Points.
HADOOP-18068. "upgrade AWS SDK to 1.12.132" broke the access point endpoint
translation.
Correct endpoints should start with "s3-accesspoint.", after SDK upgrade they start with
"s3.accesspoint-" which messes up tests + region detection by the SDK.

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.
This patch does not fix the underlying leak. When auditing is enabled,
long-lived threads will retain references to the audit managers
of S3A filesystem instances which have already been closed.

Completely removes S3Guard support from the S3A codebase.
If the connector is configured to use any metastore other than
the null and local stores (i.e. DynamoDB is selected) the s3a client
will raise an exception and refuse to initialize.
This is to ensure that there is no mix of S3Guard enabled and disabled
deployments with the same configuration but different hadoop releases
-it must be turned off completely.
The "hadoop s3guard" command has been retained -but the supported
subcommands have been reduced to those which are not purely S3Guard
related: "bucket-info" and "uploads".
This is major change in terms of the number of files
changed; before cherry picking subsequent s3a patches into
older releases, this patch will probably need backporting
first.
Goodbye S3Guard, your work is done. Time to die.

Cut modtime-based rename recovery as object modification time
is not updated during rename operation.
Applications will have to use etag API of HADOOP-17979
and implement it themselves.
Why not do the HEAD and etag recovery in ABFS client?
Cuts the IO capacity in half so kills job commit performance.
The manifest committer of MAPREDUCE-7341 will do this recovery
and act as the reference implementation of the algorithm.

Addresses transient failures in the following test classes:
* ITestAbfsStreamStatistics: Uses a filesystem level static instance to record read/write statistics, which also tracks these operations in other tests running in parallel. Marked for sequential-only run to avoid transient failure
* ITestAbfsRestOperationException: The use of a static member to track retry count causes transient failures when two tests of this class happen to run together. Switch to non-static variable for assertions on retry count

This switches the default behavior of S3A output streams
to warning that Syncable.hsync() or hflush() have been
called; it's not considered an error unless the defaults
are overridden.
This avoids breaking applications which call the APIs,
at the risk of people trying to use S3 as a safe store
of streamed data (HBase WALs, audit logs etc).
