chore: using env variables to choose test platform

TEST_PLATFORM will dictate which platform is used (KinD, EKS, etc.)
CREATE_CLUSTER decides whether or not we use an existing cluster or create a new one for the test

new package.json "scripts":
test:integration:kind will run the integration test on a new KinD cluster
test:integration:eks will run the integration test on an existing EKS cluster
test:integration will remain the same (as :kind) for backwards compatibility, for now
