0.9-beta broken for ipv4 only systems

[databus23]

We are running k8s on bare metal and don't have the ipv6 kernel model loaded.

With the current beta images this fails with the following error:

Error: exit status 1
nginx: the configuration file /tmp/nginx-cfg712046524 syntax is ok
2017/03/03 14:17:49 [emerg] 280#280: socket() [::]:80 failed (97: Address family not supported by protocol)
nginx: [emerg] socket() [::]:80 failed (97: Address family not supported by protocol)
nginx: configuration file /tmp/nginx-cfg712046524 test failed

This obviously comes from this pull request #34

This allows a brave user to run this in host networking mode and support
ipv6.

Unfortunately it seems this breaks the nginx controller for the coward users that don't have ipv6 enabled. :)

This is merged to master #356

[databus23]

@pieterlange from the looks this won't fix the problem. nginx complains about [::]:80 thats not changed in the mentioned commit.

@databus23 please take take a look on #371

@databus23 please check if the image quay.io/aledbf/nginx-ingress-controller:0.71 solves the issue.
Contains this fix.

Hi @aledbf,
Thanks for looking into this.
I just tested using your image. Unfortunately this does not fix the issue for me. I still get the same "address family not supported" error as @databus23.

@gianrubio I can confirm that #371 fixes this problem.
