This updates the testing/deployer (aka "topology test") framework to conditionally
configure and launch catalog constructs using v2 resources. This is controlled via a
Version field on the Node construct in a topology.Config. This only functions for a
dataplane type and has other restrictions that match the rest of v2 (no peering, no
wanfed, no mesh gateways).
Like config entries, you can statically provide a set of initial resources to be synced
when bringing up the cluster (beyond those that are generated for you such as
workloads, services, etc).
If you want to author a test that can be freely converted between v1 and v2 then that
is possible. If you switch to the multi-port definition on a topology.Service (aka
"workload/instance") then that makes v1 ineligible.
This also adds a starter set of "on every PR" integration tests for single and multiport
under test-integ/catalogv2
