[XTF,benchmark,v1,0/4] XTF: add micro benchmarks

Message

Dear all,

I added a benchmark category to XTF, and added functions to measure time in the
guest. Finally, I added a first micro benchmark that measures the time to call a
specified hypercall, and print the average time the hypercall takes.

The added category should be useful to implement further micro benchmarks. I
already implemented a few more that I will publish once the environment is
agreed on.

Best,
Norbert
