Add support for a static IP for Fabric pipelines for SFTP

Fabric's SFTP support is great EXCEPT for the fact that there currently isn't any way to provide external users with a static IP address for IP whitelist requirements. Some organizations may be averse to whitelisting the wide range of Azure IPs that might be required, which limits the usage of Fabric's SFTP activity. This is a pain as there are often data ingestion jobs that may need to route files through Fabric processes and then send something out again.

Please add a no-code option for the provisioning of a static IP for Fabric Data Factory pipelines similar to what can be accomplished with Azure Data Factory and a self-hosted integration runtime.
