Redirection from pages to docker registry
### Summary
Hi everybody,
*I'm posting my issue here because I didn't get any help on the GitLab Pages issue tracker (gitlab-pages#210)*
My instance is acting very strangely. I'm using GitLab 11.8.0 with GitLab Pages 1.5.0 and my pages are stored under `*.nowtryz.com`. I checked my DNS records and everything seems good, so is there a bug?
Thanks a lot for the hard work you do.
### Steps to reproduce
- Try to access http://whatever.nowtryz.com/whatever.
### What is the current *bug* behavior?
The heck is that when I try to access http://whatever.nowtryz.com/whatever, I'm redirected to https://registry.nowtryz.net:4567/whatever which is the address of my Docker registry.
### What is the expected *correct* behavior?
I should see the `whatever/whatever`'s `pages` artifacts (which doesn't exist but the result is the same).
### Output of checks
Using `gitlab-ctl tail gitlab-pages`, I see that the pages ip is in use:
```
2019-03-11_19:01:05.72115 time="2019-03-11T19:01:05Z" level=fatal error="listen tcp 51.68.57.119:80: bind: address already in use"
2019-03-11_19:01:06.74802 time="2019-03-11T19:01:06Z" level=info msg="GitLab Pages Daemon" revision=869b94c version=1.5.0
```
And that seems to be true because the result of `netstat -peanut` from inside the docker container is showing the following:
```
tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 0 119002070 743/nginx
```
But I cannot find any way to prevent nginx from listening to all addresses...

### Possible fixes
If there is no specific IP set for the registry to listen, it listens to all addresses instead of the main instance one. So just use the main instance listened to address as the default address for the registry.
