Helm chart - feature proposal: alternate git-ssh hostname

Problem to solve

Our corporate firewall blocks connections to port 22. Because we can only connect to ports 80 and 443, we would like to have git-ssh on port 443 as with altssh.gitlab.com. However, because 443 is already in use, this would require an alternate git-ssh hostname.

Intended users

Everyone at our organization (Premium self-hosted customers)

Proposal

We would like to be able to select an alternate git-ssh hostname using the helm chart values. Because this would not be an HTTP service this would probably require an additional ingress to be created.

Permissions and Security

Tiller permission is required to deploy the helm chart.
