* Usage:
* export-sync-bundle --target cluster_std-alone-instance [--retrieve ]
*[file_name]
*
* --target Cluster or stand alone server instance (required)
* --retrieve When true, the zip file is downloaded under the specified file_name in local machine
* When false, the zip file is exported under the the specified file_name on DAS
* Default value is false. (optional)
*
* file_name Specifies the file name and location of the synchronized content.
* If file_name is not specified and --retrieve=false, the default value is
* install-root/domains/domain_name/sync/-sync-bundle.zip.
* If file_name is not specified and --retrieve=true, the default value is
