The Oslo libraries have moved all of their code out of the 'oslo' namespace package into per-library packages. The namespace package was retained during kilo for backwards compatibility, but will be removed by the liberty-2 milestone. This change removes the use of the namespace package, replacing it with the new package names. The patches in the libraries will be put on hold until application patches have landed, or L2, whichever comes first. At that point, new versions of the libraries without namespace packages will be released as a major version update. Please merge this patch, or an equivalent, before L2 to avoid problems with those library releases. Blueprint: remove-namespace-packages https://blueprints.launchpad.net/oslo-incubator/+spec/remove-namespace-packages Change-Id: I975592f3694be42d52685ebf606f6d3012caf1a8
