[Feat]: Get the kickstart.sh MD5 sum by file instead from the website

[AlwinAntreich]

Problem

I am installing netdata on PXE booted systems without persistent storage. For this reason I've automated the whole setup. I would like to automatically verify the downloaded kickstart.sh with its MD5 sum. Currently I have to be aware when the sum changed to update a file on our webserver.

Hopefully, I've just missed the place where the checksum is on github. :sweat_smile:

Description

I'd like to curl https://my-netdata.io/kickstart.sh.md5sum (or similar) which contains the MD5 sum (eg. md5sum kickstart.sh), so it can be used directly in scripts to verify the downloaded file. Thank you.

Hello @AlwinAntreich, thank you for your input, this might also be a trouble for others. I think we can also add it to the GH

The checksum provided on the website is wrong. :( https://learn.netdata.cloud/docs/installing/one-line-installer-for-all-linux-systems

I didn't want to open a new issue, as it relates to the above solution.

EDIT: The checksum is from the master version. https://raw.githubusercontent.com/netdata/netdata/master/packaging/installer/kickstart.sh
