This patch will introduce early kdump test.

It reuses the code of nfs kdump test, in order to setup 2 seperated VMs, one(the client) for trigger the early kdump and crash, the other(the server) for saving vmcore and check if vmcore exists. In order to minimize the repetted code, a soft link is made to copy the same server side code.
