This is a followup to PR:
HADOOP-19045. S3A: Validate CreateSession Timeout Propagation (#6470)
Remove all declarations of fs.s3a.connection.request.timeout
in
- hadoop-common/src/main/resources/core-default.xml
- hadoop-aws/src/test/resources/core-site.xml
New test in TestAwsClientConfig to verify that the value
defined in fs.s3a.Constants class is used.
This is brittle to someone overriding it in their test setups,
but as this test is intended to verify that the option is not
explicitly set, there's no workaround.

The option fs.s3a.classloader.isolation (default: true) can be set to false to disable s3a classloader isolation;
This can assist in using custom credential providers and other extension points.

Improves region handling in the S3A connector, including enabling cross-region support
when that is considered necessary.
Consult the documentation in connecting.md/connecting.html for the current

Cut out S3 Select
* leave public/unstable constants alone
* s3guard tool will fail with error
* s3afs. path capability will fail
* openFile() will fail with specific error
* s3 select doc updated
* Cut eventstream jar
* New test: ITestSelectUnsupported verifies new failure
handling above

New test ITestCreateSessionTimeout to verify that the duration set
in fs.s3a.connection.request.timeout is passed all the way down.
This is done by adding a sleep() in a custom signer and verifying
that it is interrupted and that an AWSApiCallTimeoutException is
raised.
+ Fix testRequestTimeout()
* doesn't skip if considered cross-region
* sets a minimum duration of 0 before invocation
* resets the minimum afterwards

Address JDK bug JDK-8314978 related to handling of HTTP 100
responses.
https://bugs.openjdk.org/browse/JDK-8314978
In the AbfsHttpOperation, after sendRequest() we call processResponse()
method from AbfsRestOperation.
Even if the conn.getOutputStream() fails due to expect-100 error,
we consume the exception and let the code go ahead.
This may call getHeaderField() / getHeaderFields() / getHeaderFieldLong() after
getOutputStream() has failed. These invocation all lead to server calls.
This commit aims to prevent this.
If connection.getOutputStream() fails due to an Expect-100 error,
the ABFS client does not invoke getHeaderField(), getHeaderFields(),
getHeaderFieldLong() or getInputStream().
getResponseCode() is safe as on the failure it sets the
responseCode variable in HttpUrlConnection object.

This update ensures that the timeout set in fs.s3a.connection.request.timeout is passed down
to calls to CreateSession made in the AWS SDK to get S3 Express session tokens.

Add new option fs.s3a.checksum.validation, default false, which
is used when creating s3 clients to enable/disable checksum
validation.
When false, GET response processing is measurably faster.
