Tao Liu aa9e70349b selftest: Add early kdump test
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.
