We moved quite suddenly to deploying the wildfly/wildfly repo output to Maven Central instead of to JBoss Nexus and as a result we left a fair amount of cruft behind related to deploying to JBoss Nexus. Clean this out.

See for example https://github.com/wildfly/wildfly/pull/19658/changes#r2816713092. I'm sure there is plenty more.

This is a good one to write down a plan of what you'll do (different categories of things you identify that aren't needed, what they were, why not needed) and let people know your plan. Don't force PR reviewers to figure out what the things you are removing were for.
