Changes

• Packaging has been split into a runtime package (rocalution) and a development package (rocalution-devel): The development package depends on the runtime package. When installing the runtime package, the package manager will suggest the installation of the development package to aid users transitioning from the previous version's combined package. This suggestion by package manager is for all supported operating systems (except CentOS 7) to aid in the transition. The suggestion feature in the runtime package is introduced as a deprecated feature and will be removed in a future ROCm release.
