nova/doc/README.rst missing remark about oslo.sphinx

[Mike Spreitzer]

nova/doc/README.rst describes how to build the nova developer documentation but omits mention of oslo.sphinx. The doc build requires oslo.sphinx, but oslo.sphinx is not included in requirements.txt (because oslo.sphinx is not needed to run nova). It suffices to pip install oslo.sphinx; nova's test-requirements.txt includes oslo.sphinx, so an environment that also includes those items is good for doc building. nova/doc/README.rst should be enhanced with such an explanation.

This bug was found in nova master pulled on Jan 2, 2014.

    Add explicit discussion of dependencies to README.rst

    Noted that building the documentation has more dependencies
    than merely running Nova.
    Noted that the standard development environment is sufficient.
    Noted that the standard runtime environment plus oslo.sphinx
    is sufficient.
