Write error details in FlowFile attributes for FetchAzureDatalakeStorage

Processors such as `PutS3Object` or `FetchHDFS` writes failure reasons as a flowfile attribute. Currently `FetchAzureDatalakeStorage` logs failures in the logs, but sets no attributes that indicate the failure and the reasons. 

This issue would like to add a flowfile attribute to store error and the details of the failure for `FetchAzureDatalakeStorage`.
