CLI to operate archives managed by Storage Service (#2450)

* Add API for listing storage service archives
If id is mentioned we allow user to download specific
archive. If id is not mentioned we list all archives
present with storage service.
This will allow us to build CLI with storage service
and help users to debug storage service.
* Added commands for storagesvc cli and functionalities
* Reusing code and added geturl and download.
* Fixed geturl for localstorage.
* Fixed description of fission archive command
* Added unit tests for function getstorageurl
* Added integration test for archive cli
