Improve documentation on Kubernetes logging
https://docs.gitlab.com/ee/administration/logs.html provides locations for files that admins may need to access. The file location is generally only provided for Omnibus installs, but not for other installation methods.
Helm installs in particular are lacking sufficient documentation. With the deployment broken up into 19 different pods, where do we even start to look for each log?
Currently, not all services follow the Kubernetes convention of logging to stdout/stderr, so the logs might be found elsewhere in the file system, and even conventional logs are likely specific to a certain pod rather than collected in a centralized location. Therefore when "check the logs" is part of the troubleshooting process, the details are missing for alternate installation methods.
