[HADOOP-17876] ABFS to log @ debug each config option *And where it comes from*

• Type: Sub-task
• Status: Open
• Priority: Minor

Description

as with the other stores, there's a lot of options in abfs related to authentication, and when they are misconfigured, nothing works.

cloudstore's storediag can print out the options and their origins, but it's a command line tool, so cannot debug what applications like spark or hive are getting.

Proposed: as each config option is resolved, print out where it came from, including which jcecks credential provider.
