This adds an option to disable "empty directory" marker deletion,
so avoid throttling and other scale problems.
This feature is *not* backwards compatible.
Consult the documentation and use with care.

Fixes a condition which can cause job commit to fail if a task was
aborted < 60s before the job commit commenced: the task abort
will shut down the thread pool with a hard exit after 60s; the
job commit POST requests would be scheduled through the same pool,
so be interrupted and fail. At present the access is synchronized,
but presumably the executor shutdown code is calling wait() and releasing
locks.
Task abort is triggered from the AM when task attempts succeed but
there are still active speculative task attempts running. Thus it
only surfaces when speculation is enabled and the final tasks are
speculating, which, given they are the stragglers, is not unheard of.
Note: this problem has never been seen in production; it has surfaced
in the hadoop-aws tests on a heavily overloaded desktop

DETAILS: WASB depends on the Azure Storage Java SDK. There is a concurrency
bug in the Azure Storage Java SDK that can cause the results of a list blobs
operation to appear empty. This causes the Filesystem listStatus and similar
APIs to return empty results. This has been seen in Spark work loads when jobs
use more than one executor core.
See Azure/azure-storage-java#546 for details on the bug in the Azure Storage SDK.
TESTS: A new test was added to validate the fix. All tests are passing:
wasb:
mvn -T 1C -Dparallel-tests=wasb -Dscale -DtestsThreadCount=8 clean verify
Tests run: 248, Failures: 0, Errors: 0, Skipped: 11

DETAILS:
1) The authentication version in the service has been updated from Dec19 to Feb20, so need to update the client.
2) Add support and test cases for getXattr and setXAttr.
3) Update DelegationSASGenerator and related to use Duration instead of int for time periods.
4) Cleanup DelegationSASGenerator switch/case statement that maps operations to permissions.
5) Cleanup SASGenerator classes to use String.equals instead of ==.
TESTS:
Added tests for getXAttr and setXAttr.

S3A delegation token providers will be asked for any additional
token issuers, an array can be returned,
each one will be asked for tokens when DelegationTokenIssuer collects
all the tokens for a filesystem.
