for one of the HTTP headers is not in the correct format.".

> ABFS: Update to target 2018-11-09 REST version for ADLS Gen 2

>    Affects Versions: 3.2.0

> This update to the latest REST version (2018-11-09) will make the following 
> changes to the ABFS driver:
> 1) The ABFS implementation of getFileStatus currently requires read 
> permission.  According to HDFS permissions guide, it should only require 
> execute on the parent folders (traversal access).  A new REST API has been 
> introduced in REST version "2018-11-09" of ADLS Gen 2 to fix this problem.
> 2) The new "2018-11-09" REST version introduces support to i) automatically 
> translate UPNs to OIDs when setting the owner, owning group, or ACL and ii) 
> optionally translate OIDs to UPNs in the responses when getting the owner, 
> owning group, or ACL.  Configuration will be introduced to optionally 
> translate OIDs to UPNs in the responses.  Since translation has a performance 
> impact, the default will be to perform no translation and return the OIDs.
