Ceph

I am in the process of creating a new Python component in Ceph and I've been forced to add these:

README.rst, requirements.txt, test-requirements.txt

Because the module wants them:

set(py_srcs setup.py README.rst requirements.txt test-requirements.txt ${name})

The build fails if any of those aren't present, like

[  4%] [  4%] make[2]: *** No rule to make target `../src/ceph-volume/requirements.txt', needed by `src/ceph-volume/requirements.txt'.  Stop.

It is absolutely unnecessary to require a `test-requirements.txt` and a `requirements.txt`. If some other Ceph component wishes to include those, then it should
be up to that component to find a way to include them and not force everything else to add empty files to be able to build Ceph.
