5c648f22c1 add draft to integrate a hypervisor directly in the proxy 
- this reduce the overhead because the boot time is smaller in
  comparsion to qemu
- furthermore, a more direct communication via VM_EXISTS is possible
- the current version doesn't support a network interface

The hypervisor based on KVM and is called uhyve. You could test the
hypervisor with following command:

HERMIT_ISLE=uhyve HERMIT_VERBOSE=1 tools/proxy usr/tests/hello
