The swift:// connector for openstack support has been removed.
The hadoop-openstack jar remains, only now it is empty of code.
This is to ensure that projects which declare the JAR a dependency
will still have successful builds.

Updating the hadoop version of branch-3.3 to 3.3.9-SNAPSHOT
pending agreement on what number its future release should take.
Using 3.3.9-SNAPSHOT puts space in for other incremental releases,
while avoiding creating JIRA release ordering and autocompletion
confusion the way adding a 3.3.10 or higher version would do.

These changes ensure that sequential files are opened with the
right read policy, and split start/end is passed in.
As well as offering opportunities for filesystem clients to
choose fetch/cache/seek policies, the settings ensure that
processing text files on an s3 bucket where the default policy
is "random" will still be processed efficiently.
This commit depends on the associated hadoop-common patch,
which must be committed first.

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 strips out all the -p preservation options which have already been
processed when uploading a file before deciding whether or not to query
the far end for the status of the (existing/uploaded) file to see if any
other attributes need changing.
This will avoid 404 caching-related issues in S3, wherein a newly created
file can have a 404 entry in the S3 load balancer's cache from the
probes for the file's existence prior to the upload.
It partially addresses a regression caused by HADOOP-8143,
"Change distcp to have -pb on by default" that causes a resurfacing
of HADOOP-13145, "In DistCp, prevent unnecessary getFileStatus call when
not preserving metadata"

This avoids overwrite consistency issues with S3 and other stores -though
given S3's copy operation is O(data), you are still best of using -direct
when distcp-ing to it.

This uses the length of the file known at the start of the copy to determine the amount of data to copy.
* If a file is appended to during the copy, the original bytes are copied.
* If a file is truncated during a copy, or the attempt to read the data fails with a truncated stream,
distcp will now fail. Until now these failures were not detected.

Reverting due to test failures if ~/.Trash not present during test setup.
This reverts commit ee3115f488.
Change-Id: Icbeeb261570b9131ff99d765ac0945c335b26658
Adding a protected-scope getter for the DistCpOptions, so that a subclass does
not need to save its own copy of the inputOptions supplied to its constructor,
if it wishes to override the createInputFileListing method with logic similar
to the original implementation, i.e. calling CopyListing#buildListing with a path and input options.
