feat: add connection_max_age config

[uosjead]

Description

Currently seeing some occasional connectivity issues running behind a NAT gateway - where connections are limited to 5 minutes. The gitlab-runner config by defaults limits connections to 15 minutes. Was looking to set the connection_max_age setting with the module, but could not find an option to do so.

Add connection_max_age as a configurable option to the runner config.
