HADOOP-17385. ITestS3ADeleteCost.testDirMarkersFileCreation failure (#2473). Contributed by Steve Loughran

The addition of deprecated S3A configuration options in HADOOP-17318
triggered a reload of default (xml resource) configurations, which breaks
tests which fail if there's a per-bucket setting inconsistent with test
setup.

Creating an S3AFS instance before creating the Configuration() instance
for test runs gets that reload out the way before test setup takes
place.

Along with the fix, extra changes in the failing test suite to fail
fast when marker policy isn't as expected, and to log FS state better.

Rather than create and discard an instance, add a new static method
to S3AFS and invoke it in test setup. This forces the load
