makefile:hypershift: initial make target (openshift#995)

Add initial make target for running e2e tests on hypershift environment.

On later PR an actual call for the e2e tests will be added.

`HYPERSHIFT_MANAGEMENT_CLUSTER_KUBECONFIG` and
`HYPERSHIFT_HOSTED_CLUSTER_KUBECONFIG` are defined
by the u/s ci and provided the kubeconfig file path
for the management and hostet cluster respectively.
