Max Altgelt 6f05e33feb fix: Correct incorrect message / keyword usage
Correct a number of rules where message or keyword were incorrectly used
as field names in events (typically windows event logs). However, neither
field actually exists and as such these strings could never match.

Florian Roth 08883c8e32 refactor: removed old rule that uses Message field
Rules that use the "Message" field are prone to localisation issues and should be avoided whenever possible.

We can build what we call "keyword" rules in these cases and simply combine string values that are searched in the raw data as 1 of them or all of them. (see specs for details)

Jon Galarneau 1544a351a3 Correcting regex in win_modif_of_services_for_via_commandline.yml
The ^ symbol designates the beginning of the string, but in this rule it is clearly intended to be the end of the string.
