bin/get_formulas.py: don't verify the SSL cert for the gitlab.i.o.o repos
    
    We are using a freeipa created cert for gitlab.i.o.o, thus the
    containers created by CI runner can't verify it. This creates the issue
    that we can't fetch the remote. Since we plan to switch to letsencrypt
    wildcards as soon as they are available, it's easier for now to pass an
    environment variable to disable the SSL verification for this command
