Workaround for dnf+docker version race condition
In some versions of dnf the rpm database can require maintenance after usage. Unfortunately, this trips up get_version_output in the openshift_facts library as the maintenance may interrupt the STDOUT stream. This makes the resulting data returned from get_version_output malformed and unparsable. This change adds an rpm --rebuilddb command before requesting docker version output when the ansible package manager is dnf. This causes the STDOUT maintenance messages to no longer interrupt the expected yaml stream as well as releases locks in the rpm database.
