[meta-virtualization] [m-c-s][PATCH 15/21] python-oslo.utils: Error fix

[Li Xin]

python-oslo.utils depends on python-pbr, and will download pbr modules
in the step of do_compile.
If your network is not very well,errors will occur as following:
  Download error on https://pypi.python.org/simple/pbr/:
  [Errno -5] No address associated with hostname -- Some packages may not be found!
  Couldn't find index page for 'pbr' (maybe misspelled?)
  No local packages or download links found for pbr
