Install base_packages earlier

Currently, openshift_facts requires pyyaml to be installed.
This package is installed via init/base_packages.yml, which
is currently called after init/facts.yml.  This results
in a situation where installs will fail due to missing
python dependency.

This commit splits init/facts.yml into two, and
allows base_packages.yml to be run before the
openshift_facts.py plugin is executed.
