Multi-workspace URL support

This feature allows customers to set up multiple URLs for their workspace (subdomains of cloud.com), and use these URLs as policy input. StoreFront on-premises already allows an installation to utilize multiple workspace URLs to provide tailored use cases and resources to different areas of an installation. The support of Multi-Workspace URL aims to bring this capability to the Workspace platform by allowing customers to select branding, identity providers, and resources filtering based on the Workspace URL.
