How can I configure the web.external-url

[noesberger]

Hi

We need to specify the web.external-url for the pushgateway the same way we can for the prometheus itself.

In the template the only option I found to add additional configuration is in the web_config file: --web.config.file=/etc/pushgateway/web_config.yml with the variable: pushgateway_http_server_config

But I can't find any documentations about what options to configure. And using web.external-url= is always failing. Any hints?
