[docker] add missing settings to docker kibana.yml

[111andre111]

To https://github.com/elastic/kibana/blob/master/src/dev/build/tasks/os_packages/docker_generator/resources/bin/kibana-docker

I checked against that an excel sheet manually generated
kibana-settings.xlsx

and the outcome were these settings missing in docker.

Referring to issue
#39592
there were added lots of settings.
So now is the question:

1. Is there a way to generate a complete settings map against the source code because my manual approach may be not complete?

2. Should we still add these settings to docker entrypoint variables until this issue will be applied?

There isn't a high level way to aggregate between the new and old platform. I tried to hack something out a while back and was able to get all non deprecated settings, so it wasn't great.

Going forward the approach we want to take is to remove all snake case settings, and then remove that whitelist entirely. We'll be run a case change on everything.
