add support for specifying env parameters for kubetest2-gce deployer

[upodroid]

/cc @dims @tzneal

~In theory, all we need to do to run arm e2e tests on GCP is to compile arm binaries, create VMs with arm machine types and use the arm images~

k/k cluster scripts are too buggy right now to support arm64 building, but the feature is required for passing env variables to the kube-*.sh scripts.

I'll create a separate job to run the legacy-mode tests

It looks like the CI failed because some hardcode in k/k shell scripts. I raise a PR about env KUBE_BUILD_PLATFROMS in https://github.com/kubernetes/kubernetes/pull/120100

@michelle192837 Can you approve this, please? we can ignore the failing AWS test as it is unrelated to this change.
