This defines what output streams and especially those which implement
Syncable are meant to do, and documents where implementations (HDFS; S3)
don't. With tests.
The file:// FileSystem now supports Syncable if an application calls
FileSystem.setWriteChecksum(false) before creating a file -checksumming
and Syncable.hsync() are incompatible.

The ABFS connector now implements listStatusIterator() with
asynchronous prefetching of the next page(s) of results.
For listing large directories this can provide tangible speedups.
If for any reason this needs to be disabled, set
fs.azure.enable.abfslistiterator to false.

When 403 is returned from an ABFS HTTP call, an AccessDeniedException is raised.
The exception text is unchanged, for any application string matching on the getMessage() contents.

DETAILS:
The previous commit for HADOOP-17397 was not the correct fix. DelegationSASGenerator.getDelegationSAS
should return sp=p for the set-permission and set-acl operations. The tests have also been updated as
follows:
1. When saoid and suoid are not specified, skoid must have an RBAC role assignment which grants
Microsoft.Storage/storageAccounts/blobServices/containers/blobs/modifyPermissions/action and sp=p
to set permissions or set ACL.
2. When saoid or suiod is specified, same as 1) but furthermore the saoid or suoid must be an owner of
the file or directory in order for the operation to succeed.
3. When saoid or suiod is specified, the ownership check is bypassed by also including 'o' (ownership)
in the SAS permission (for example, sp=op). Note that 'o' grants the saoid or suoid the ability to
change the file or directory owner to themself, and they can also change the owning group. Generally
speaking, if a trusted authorizer would like to give a user the ability to change the permissions or
ACL, then that user should be the file or directory owner.

DETAILS:
This change adds config key "fs.azure.enable.conditional.create.overwrite" with
a default of true. When enabled, if create(path, overwrite: true) is invoked
and the file exists, the ABFS driver will first obtain its etag and then attempt
to overwrite the file on the condition that the etag matches. The purpose of this
is to mitigate the non-idempotency of this method. Specifically, in the event of
a network error or similar, the client will retry and this can result in the file
being created more than once which may result in data loss. In essense this is
like a poor man's file handle, and will be addressed more thoroughly in the future
when support for lease is added to ABFS.
