Upgrade Kubernetes nginx Ingress application via Kubernetes integration
> Why is this still using `0.10.2`? This is *very* out of date. [Upstream](https://github.com/helm/charts/blob/master/stable/nginx-ingress/values.yaml#L8), [gitlab/gitlab](https://gitlab.com/charts/gitlab/blob/master/charts/nginx/values.yaml#L12)
First noticed in https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/27582#note_166353581, even though the helm chart is quite recent we seem to have pinned the image to a very old version.
## Proposal
Remove the pin to the image.
This upgrades us from [0.10.2](https://github.com/kubernetes/ingress-nginx/blob/master/Changelog.md#0102) to whatever is latest in https://github.com/kubernetes/ingress-nginx/blob/master/Changelog.md
