cert tools should warn or error when missing config info will result in invalid cert

[stuartf]

I created a cert with no revocation_list in the conf.ini this resulted in the cert having revocation_list: null which cannot be imported to the iOS wallet. The tool shouldn't output broken certs.

The Cert Tools already give a warn to a few parameters:

create-certificate-template: error: the following arguments are required: --issuer_name, --issuer_id, --certificate_title, --criteria_narrative, --badge_id

Yout can add the parameter revocation_list to the list of required parameters and make a pull.

How exactly did you generate your conf.ini, I'm trying to generate one and I receive TypeError: join() argument must be str or bytes, not 'NoneType':

create-certificate-template -c '/home/pc/Documents/Block/conf.ini' --issuer_email '[email protected]' --issuer_name 'name' --issuer_id 'id' --certificate_title 'title', --criteria_narrative 'criteria' --badge_id 'badge id'

I have fixed it, this module don't support Python 3.7, the function generic_path (/lib/python3.5/genericpath.py) can't get the parameters
