don't overwrite default config files

[senecaso]

• allow the value provided CFG files to provide a basis for the dedicated sever, then only add/overwrite specific ones as provided in the image
• don't download entry.sh from github using wget. Instead, bake the script into the image from the local file system
• add .gitattributes to force CFG files to be treated as binary files so that git wont change the line endings on them (just in case that is important to CSGO)
• remove the old CFG tarball and replace it with just the CFG files which are added (ie: esl*.cfg)
• dont set "warmup" related cvars in server.cfg. Most of these values were the defaults anyway, and by setting mp_warmup_pausetimer there, it made it so that Danger Zone servers were stuck in the warmup forever with no way to play. If this behaviour is desiratable, it can be achieved by adding -e ADDITIONAL_ARGS="+mp_warmup_pausetimer 1" to the launch command.

Here's the Docker Hub log. Seems like you moved the etc directory into bullseye. This is why it's erroring out.

I refactored the build script a bit to better accommodate the directory changes. Looks like it works, but perhaps there is another build somewhere which is failing. Let me know if there are any other issues.

[senecaso]

its worth noting that this would be a breaking change for anyone attempting to set DLURL to download the tarball from a different URL, since that is no longer done. I see that someone specifically made changes in a recent commit to handle this situation, but I believe this approach is more flexible, as the user can just mount a new volume into the container to /etc/csgo/ which contains all of the config scripts they want to use, and it will use them. The problem with downloading a tarball at runtime is that it could pose security risks. If an attacker is able to influence that tarball or the URL in any way, they could inject arbitrary binaries into your container at runtime.

This approach could potentially be improved by copying 2 different paths, /etc/csgo/base and /etc/csgo/custom which would allow the user to mount a volume to /etc/csgo/custom to only add new config scripts, but to also mount /etc/csgo/base if they didnt want to use any of the provided ones. If you feel that would be useful, let me know and I could add it quite quickly.
