PoC: Network simulation framework (#1555)
* simv2: wip

* simulation: exec adapter start/stop

* simulation: add node status to exec adapter

* simulation: initial simulation code

* simulation: exec adapter, configure path to executable

* simulation: initial docker adapter

* simulation: wip kubernetes adapter

* simulation: kubernetes adapter proxy

* simulation: implement GetAll/StartAll/StopAll

* simulation: kuberentes adapter - set env vars and resource limits

* simulation: discovery test

* simulation: remove port definitions within docker adapter

* simulation: simplify wait for healthy loop

* simulation: get nat ip addr from interface

* simulation: pull docker images automatically

* simulation: NodeStatus -> NodeInfo

* simulation: move discovery test to example dir

* simulation: example snapshot usage

* simulation: add goclient specific simulation

* simulation: add peer connections to snapshot

* simulation: close rpc client

* simulation: don't export kubernetes proxy server

* simulation: merge simulation code

* simulation: don't export nodemap

* simulation: rename SimulationSnapshot -> Snapshot

* simulation: linting fixes

* simulation: add k8s available helper func

* simulation: vendor

* simulation: fix 'no non-test Go files' when building

* simulation: remove errors from interface methods where non were returned

* simulation: run getHealthInfo check in parallel
