This adds a new option fs.s3a.bucket.probe, range (0-2) to
control which probe for a bucket existence to perform on startup.
0: no checks
1: v1 check (as has been performend until now)
2: v2 bucket check, which also incudes a permission check. Default.
When set to 0, bucket existence checks won't be done
during initialization thus making it faster.
When the bucket is not available in S3,
or if fs.s3a.endpoint points to the wrong instance of a private S3 store
consecutive calls like listing, read, write etc. will fail with
an UnknownStoreException.

Adds a new service code to recognise accounts without HTTP support; catches
that and considers such a responset a successful validation of the ability of the
client to switch to http when the test parameters expect that.

Followup to the main openFile().withStatus() patch.
It turns out that this broke the hive builds, which
was not well appreciated.
This patch lists places to review in the hadoop codebase,
and external projects where changes are likely to cause problems.
