Custom Go-based dataplane for xDS control plane APIs

[praveingk]

Re-creating based on #44
@elevran : Addressed most of the comments from the previous PR, except the dataplane API refactoring (using controller) suggested by @orozery which would be done as another PR after removing the old dataplane code.

@praveingk Can you add an e2e test for this?
Perhaps similar to the tests/k8s.sh.
I plan to write a go test suite for setting up kind clusters with controlplane / dataplane (and ditch the current shell script test).
But anyhow, I think you may need to add a cl-adm flag for using the go-dataplane.

I have added dataplane type in cl-adm, and edited docker script. Please check c63110c and 7ac823f and feel free to edit it accordingly.
The e2e tests can be run as ./tests/k8s.sh clink default is envoy.

Can you also change the github actions workflow to run tests/k8s.sh with the go dataplane?

@praveingk Can you also add a switch case check to PeerOptions::Run() to verify that DataplaneType has a valid value?

@orozery reading through the conversation it seems all requests have been addressed. Is there anything else that needs to be done? If not - please mark approval so it can be merged
