Create a domain for feature requests

[horner]

See #468

we need to setup cloudflare for wikigdrive so we can make docker containers for feature branches. We need a wildcard domain to allow us to make .dev.wikigdrive.com.

*.dev will require us to manage certificates since cloudflare doesn't do subdomain of a subdomain for SSL.

I've setup *.wikigdrive.com to point to the dev container, so now we can do something like pr-230.wikigdrive.com
