Review comment:
       Do we need to check if the scheme prefix starts with "abfs" here to 
cover both the secure and none secure schemes without including other schemes 
that are non Azure file systems?

Review comment:
       Thanks for adding these schemes in the Map. Otherwise, it will not allow 
those schemes to be recognized as supported FileSystems.
