Subject: Add host environment setup scripts

Testing KVM4NFV project requires special host environment to get the
best result.

Two scrripts are used to setup the environment. The host-setup0.sh setup
the environment that should take effect before the kernel is bringup,
mostly the grub entries. The host-setup1.sh setup the environment that
takes effect after the kernel is up, like some sysfs entry, interrupt
affinity etc. The host-config provides the configurations.
