Fix 'Ensure DNF modules have the right stream'

This change solves bug [1]. Change introduces a new mandatory field to
DnfStreams parameter and adjusts 'Ensure DNF modules have the right
stream' task to use new field. New field is called distribution_version
and its purpose is to choose modules enabled in centos8 or in centos9.

DnfStreams parameter defines list of dnf module streams to be configured
before updating packages both on undercloud and overcloud.
