[Batch] Beta Data Plane SDK 15.0.0b3

[cRui861]

Description

Update Azure Batch Python SDK to v15.0.0b3 beta preview. No API update in this release. Changes are further detailed in the CHANGELOG.

Quick summary of changes:

• Added Long Running Operation (LRO) updates for some of our operation methods (i.e. delete_job is now begin_delete_job). These LRO updates were added for operations that could take an extended period to complete. Calling these functions will return a LROPoller that will track the operation's progress and give acess to intermediate and final statuses.
• Added a BatchExceptionPolicy to transform ODataV4Format to our own BatchErrorFormat for error handling.

If an SDK is being regenerated based on a new API spec, a link to the pull request containing these API spec changes should be included above.
