Enabling Cloud Referencing for Package Creation

Cloud referencing links package files to source files in the cloud instead of copying source files to create a package.

Important:

The source and destination of a package must be in the same cloud storage attached to an HST Server running in the cloud, or attached to the Aspera on Cloud Transfer Service (if compatible).
Faspex currently supports file storages run by these cloud providers:
- AWS (S3)
- Azure

Go to Server > File Storage and edit the file storage of the remote cloud service node. Select Enable cloud referencing.
Enable trap links for the remote storage.
For example, on Azure nodes, edit /opt/aspera/etc/trapd/azure.properties and set aspera.session.support.symlink = true.
```
# Defines whether symlink support is wished
# Default is false
aspera.session.support.symlink = true
```
Enable the configuration changes by running:
```
$ sudo service asperatrapd restart
```
Note: When creating a package, both the source and the default inbox need to be on the same cloud node for the cloud referencing feature to work.
Enable specific users to create packages from remote sources.
Go to Accounts and click the name of the user. Under Permissions, select Create packages from remote sources to enable the feature for that user.
