Add fuel-plugin-kvm to install kvmfornfv

Add fuel-plugin-kvm to install kvmfornfv

1. The installer function for kvmfornfv was in fuel-plug-qemu in
   Brahmaputra release, it will be in this new fuel-plugin-kvm for
   Colorado release for clarity
2. Deleted f_qemupluginbuild sub-directory
3. Two "# fix me" for "@sudo rm -rf kvmfornfv" instead of "@rm -rf
   kvmfornfv" in Makefiel are the temp workgrounds for some files
   generated during kvmfornfv building are owned by "root", will
   remove these workarounds after resolving this issue in
   fuel-plugin-kvm build process
