yum >=3.0.0 removes ius recipe

[mike182uk]

yum >=3.0.0 no longer includes the ius recipe. ius is now its own cookbook.

yum-ius requires Chef 11 or higher so making this a dependency would break bc with projects using older versions of Chef.

Locking the version at < 3 potentially causes issues with other cookbooks that require yum > 3 (runit, memcached etc.)

Im not sure what best approach to resolve this is. I would probably say depend on yum > 3 and yum-ius but not sure what versions of Chef this cookbook is aimed at supporting.
