File size check missing for VNFD template, parameter values file and config values file in Horizon and python-tackerclient

[vishwanath jayaraman]

As part of review https://review.openstack.org/#/c/221953/2/tacker_horizon/openstack_dashboard/dashboards/nfv/vnfmanager/forms.py lhcheng raised a good point if we needed to apply file size check for VNFD templates, Parameter value files and config files.
The horizon code at https://github.com/openstack/horizon/blob/master/openstack_dashboard/dashboards/project/instances/workflows/create_instance.py#L680-L692 for file check was referenced as part of the review comment.
Tacker community will need to decide if we want to apply file size limits and the max size to be supported.

Make sense to enforce a reasonable max file size. Useful boundary check.
