Update git submodules

* Update grenade from branch 'master'
  - Make docs build again
    
    Docs build was broken with:
    
    TypeError: __init__() got an unexpected keyword argument 'handle_io_errors'
    
    Upgrade sphinx requirements to those of a recent decade, and replace
    the oslosphinx extension and requirement with openstackdocstheme.
    
    At the same time, split the deps for the docs build out of
    test-requirements.txt and put them in docs/requiremenst.txt as the gods
    intended.
