Comment 7 for bug 1649058

This bug consists of 2 issues:

1) absence of ability to safely transport fuel-infra repos public key - this should be done on infra side
2) after #1 is finished - we need to add a stanza in provsioning manifests to import this public key into the base and bootstrap image.

Thus, we need to create an https endpoint or distribut our public key over public trusted pgp servers or set up our own pgp server to do this. After that we will create required stanza on the provisioning side.
