Support custom Fedora repos in vagrant provider

Sometimes `KUBERNETES_PROVIDER=vagrant cluster/kube-up.sh` fails due to problems
with Fedora's metalink URL:
```
Timeout was reached for https://mirrors.fedoraproject.org/metalink?repo=fedora-23&arch=x86_64 [Connection timed out after 120002 milliseconds]
```

This PR makes it possible to specify a custom Fedora repository URL:
```
export CUSTOM_FEDORA_REPOSITORY_URL=https://download.fedoraproject.org/pub/fedora/
```
