work-in-progress (very complicated) -- trying to reconcile the list at https://www.redhat.com/en/about/eulas with existing licenses in our list. Stay tuned.

Too many updates to describe them all here! In DejaCode (including the public evaluation instance) the following licenses were added or updated:

New Licenses:
rh-eula-gpl2
rh-eula-apache2
rh-standard-eula-2019

Updated Licenses:
rh-eula
rh-eula-lgpl
rh-ubi-eula-2019

@AyanSinhaMahapatra Please synchronize ScanCode appropriately and create the associated rules.

I believe that covers the appropriate licenses at https://www.redhat.com/en/about/eulas although there are a few licenses at the bottom of the page, referring to Kubernetes, that are not really "licenses" but "component notices" (from our point of view) since they get specific about the licenses that apply to various subsets of the software, and these licenses are not at all the same, or even compatible, including both Permissive and Source-Available licenses. Unless I am convinced otherwise, I don't think those belong in our license lists.
