Prototype Site-to-Site Data Transfer (via NCC or VMs) via Dual Dedicated Interconnect with POP on/off-ramp for sustained 10gbps+ throughput at the lowest latency within CA and CA to EU

This is an extension of #298
**Site to Site Data Transfer**
- Ideally use the NCC (Network Connectivity Center) - to pass BGP routing between customer sites across the GCP backbone
- https://cloud.google.com/network-connectivity/docs/network-connectivity-center/concepts/data-transfer
- with non-NCC supported workarounds in https://cloud.google.com/network-connectivity/docs/network-connectivity-center/concepts/optimal-route-advertisement (Terms of service testing waiver)
- branch https://github.com/GoogleCloudPlatform/pubsec-declarative-toolkit/tree/gh756-interconnect

**Purpose:**
- Primary: prototype a dedicated interconnection between the east/west coast of CA via the nearest POPs on both ends.
- Secondary: prototype the same connection between a POP on the other side of the world
- Maximize: sustained 10gpbs throughput from clients on both sides of the interconnect
- Minimize: latency/hops between both sides of the interconnects
- Document: all operations from the LOA to deployment
- Minimize: setup/teardown time of the interconnect
