2 Freeze Break requests

[Kevin Fenzi]

Hi folks.

2 more freeze break requests. ;)

1. I'd like to add mirror.fcix.net to tier1 mirrors
https://pagure.io/fedora-infra/ansible/pull-request/1342
This would be good to do before beta so they could help mirror that out
better.

2. switch the fails to install script to use f38 instead of f37:
https://pagure.io/fedora-infra/ansible/pull-request/1341

Both of these are pretty simple, easy to revert.

+1s?
