Access internal hosts via apex proxy. From the compute nodes we first open an SSH connection to apex, and then tunnel it through the HTTP proxy with netcat. This way we allow reaching internal GitLab repositories without requiring the user to have credentials in the remote host, while we can use multiple remotes to provide redundancy.
