> Configuration for WASB and ABFS is too complex.  The current approach is to use four
files for test configuration. 
> Both WASB and ABFS have basic test configuration which is committed to the repo (azure-test.xml
and azure-bfs-test.xml).  Currently these contain the fs.AbstractFileSystem.[scheme].impl
configuration, but otherwise are empty except for an include reference to a file containing
the endpoint credentials. 
> Both WASB and ABFS have endpoint credential configuration files (azure-auth-keys.xml
and azure-bfs-auth-keys.xml).  These have been added to .gitignore to prevent them from
accidentally being submitted in a patch, which would leak the developers storage account credentials. 
These files contain account names, storage account keys, and service endpoints.
> There is some overlap of the configuration for WASB and ABFS, where they use the same
property name but use different values.  
> 1) Let's reduce the number of test configuration files to one, if possible.
> 2) Let's simplify the account name, key, and endpoint configuration for WASB and ABFS
if possible, but still support the legacy way of doing it, which is very error prone.
> 3) Let's improve error handling, so that typos or misconfiguration are not so difficult
to troubleshoot.
