Fixes the regression caused by HADOOP-17511 by moving where the
option fs.s3a.acl.default is read -doing it before the RequestFactory
is created.
Adds
* A unit test in TestRequestFactory to verify the ACLs are set
on all file write operations.
* A new ITestS3ACannedACLs test which verifies that ACLs really
do get all the way through.
* S3A Assumed Role delegation tokens to include the IAM permission
s3:PutObjectAcl in the generated role.

This patch cuts down the size of directory trees used for
distcp contract tests against object stores, so making
them much faster against distant/slow stores.
On abfs, the test only runs with -Dscale (as was the case for s3a already),
and has the larger scale test timeout.
After every test case, the FileSystem IOStatistics are logged,
to provide information about what IO is taking place and
what it's performance is.
There are some test cases which upload files of 1+ MiB; you can
increase the size of the upload in the option
"scale.test.distcp.file.size.kb"
Set it to zero and the large file tests are skipped.

This improves error handling after multiple failures reading data
-when the read fails and attempts to reconnect() also fail.

This work
* Defines the behavior of FileSystem.copyFromLocal in filesystem.md
* Implements a high performance implementation of copyFromLocalOperation
for S3
* Adds a contract test for the operation: AbstractContractCopyFromLocalTest
* Implements the contract tests for Local and S3A FileSystems

These should be recoverable.

Introducing fs.azure.readahead.range parameter which can be set by the user.
Data will be populated in buffer for random reads as well which leads to fewer
remote calls.
This patch also changes the seek implementation to perform a lazy seek. The
actual seek is done when a read is initiated and data is not present in the buffer else
data is returned from the buffer thus reducing the number of remote storage calls.

This addresses the regression in Hadoop 3.3.1 where if no S3 endpoint
is set in fs.s3a.endpoint, S3A filesystem creation may fail on
non-EC2 deployments, depending on the local host environment setup.
* If fs.s3a.endpoint is empty/null, and fs.s3a.endpoint.region
is null, the region is set to "us-east-1".
* If fs.s3a.endpoint.region is explicitly set to "" then the client
falls back to the SDK region resolution chain; this works on EC2
* Details in troubleshooting.md, including a workaround for Hadoop-3.3.1+
* Also contains some minor restructuring of troubleshooting.md

The S3A connector supports
"an auditor", a plugin which is invoked
at the start of every filesystem API call,
and whose issued "audit span" provides a context
for all REST operations against the S3 object store.
The standard auditor sets the HTTP Referrer header
on the requests with information about the API call,
such as process ID, operation name, path,
and even job ID.
If the S3 bucket is configured to log requests, this
information will be preserved there and so can be used
to analyze and troubleshoot storage IO.

The option `fs.s3a.endpoint.region` can be used
to explicitly set the AWS region of a bucket.
This is needed when using AWS Private Link, as
the region cannot be automatically determined.

When the S3A and ABFS filesystems are closed,
their IOStatistics are logged at debug in the log:
org.apache.hadoop.fs.statistics.IOStatisticsLogging
Set `fs.iostatistics.logging.level` to `info` for the statistics
to be logged at info. (also: `warn` or `error` for even higher
log levels).

Followup to HADOOP-13327, which changed S3A output stream hsync/hflush calls
to raise an exception.
Adds a new option fs.s3a.downgrade.syncable.exceptions
When true, calls to Syncable hsync/hflush on S3A output streams will
log once at warn (for entire process life, not just the stream), then
increment IOStats with the relevant operation counter
With the downgrade option false (default)
* IOStats are incremented
* The UnsupportedOperationException current raised includes a link to the
JIRA.

The ABFS Filesystem and its input and output streams now implement
the IOStatisticSource interface and provide IOStatistics on

This moves the mock account name --which is required to never exist-- from
"mockAccount" to an account name containing a static UUID.

Moves to the builder API for AWS S3 client creation, and
offers a similar style of API to the S3A FileSystem and tests, hiding
the details of which options are client, which are in AWS Conf,
and doing the wiring up of S3A statistics interfaces to the AWS
SDK internals. S3A Statistics, including IOStatistics, should now
count throttling events handled in the AWS SDK itself.
This patch restores endpoint determination by probes to US-East-1
if the client isn't configured with fs.s3a.endpoint.
Explicitly setting the endpoint will save the cost of these probe
HTTP requests.
