import_collection task to send filepath to galaxy-importer
Currently the import_collection task sends the artifact fileobject to galaxy-importer. In galaxy-importer we want move from using the tarfile module to tar in shell.
We would like import_collection task to send the artifact filepath to galaxy-importer.
Also, currently in the fileobject we use the .storage.url property to download the artifact to a container to run "ansible-test sanity". So perhaps we can send the filepath + url instead of the opened fileobject.
