Use Fabric modules in blueprints/networking/psc-glb-and-armor

Few minor improvements along the way:

• remove unnecessary subnets (additional NAT for PSC, VMS)
• remove NOOP compute engine instance
• added url_rewrite for service b, so the service actually works as expected
• added allow-list for consumer projects that can connect to the producers PSC service
• improved curl to it uses terraform output for find the IP address
• added possibility to meaningfully create projects (using prefixes, parent etc.)

This that are different , though not sure if that's OK:

• added network in consumer project, so PSC attachment doesn't complain on missing default network, not sure if that was expected
