HADOOP-17454. [s3a] Disable bucket existence check - set fs.s3a.bucket.probe to 0 (#2593)
Also fixes HADOOP-16995. ITestS3AConfiguration proxy tests failures when bucket probes == 0
The improvement should include the fix, because the test would fail by default otherwise.

When set to 0, bucket existence checks won't be done
