Add settings of interest to server administrators that appear in
server-settings.json to the factorio.settings config. This makes it
easier to see which settings can be set there.
The automatic creation of a self-signed certificate while nice presents
several problems. To make connections not reject the self-signed
certificate the validation of TLS certificates are wholesale disabled,
decreasing the security even when properly set up and trusted
certificates are used.
To make the created self-signed certificate pass validation it is
necessary for it to list the host names it's valid for and to copy it to
each machine that intends to connect to the server. These two steps
complicate automating the process in a reliable way and will likely lead
to confused users seeking to disable TLS certificate validation as the
easy way out to problems.
For these reasons, remove the automating creation of a broke self-signed
certificate, fix validation of certificates and document how to set up
TLS properly. This makes HTTPS recommended when accessing over the
internet, but still something which must be explicitly configured.
When reducing the collection interval in Prometheus it may be necessary
to to reduce the metrics gathering timeout to ensure it's less than the
interval. Add config options to adjust the timeouts used for metrics
gathering so that these can be set accordingly.
Add option to set the the maximum amount of commands transmitted in
parallel to the game. Increasing this value allows a greater rate of
commands to be executed.
Use 45 seconds as the default heartbeat interval instead of 60. Using
60 causes connections to drop when proxied through Nginx as the default
timeout there is also 60 seconds.
