openstack tripleo deploy --networks-file should not require absolute path

A deployment with "openstack tripleo deploy --networks-file network_data.yaml ... " [1] resulted in the network_data.yaml being ignored. My rendered overcloud-resource-registry-puppet.yaml contained networks I didn't have in my network_data.yaml which are in the default like internal_api [2]. As a workaround, I used the absolute path to my network_data.yaml file it was used and not ignored and the deployment worked I expected. E.g. my overcloud-resource-registry-puppet.yaml used the ctlplane network [3] (I was only using one extra network in network_data [4]).
