apisix ingress controller e2e test suites

For running e2e test cases, a Kubernetes cluster is needed, minikube is a good choice to build k8s cluster in development environment.

Scaffold

a e2e test scaffold is prepared to run test cases easily. The source codes are in directory test/e2e/scaffold, it builds necessary running environment:

• Create a brand new namespace;
• Create etcd deployment and etcd service in the specified namespace;
• Create apisix deployment and apisix service in the specified namespace (note both the control plane and data plane are created);
• Create apisix-ingress-controller deployment in the specified namespace;
• Create a http server with kennethreitz/httpbin as the upstream.

The abovementioned steps are run before each case starts and all resources will be destroyed after the case finishes.
