Populate optional comps.xml unit fields [RHELDST-25995]

When pushing comps.xml files, if a unit already exists in Pulp, fields that have been removed from the comps.xml did not get overwritten. This resulted in unexpected older data being published from Pulp. This change extends the comps.xml parsing by giving an option to fill in all fields in comp unit classes from pulp-rpm. When the data is uploaded into pulp this will overwrite old unwanted data.
