Add ee8 modules with sources generated from ee9 sources

[olamy]

add some modules ee8 translated from ee9:

• jetty-ee8-annotations
• jetty-ee8-jaas
• jetty-ee8-nested
• jetty-ee8-plus
• jetty-ee8-security
• jetty-ee8-servlet
• jetty-ee8-servlets
• jetty-ee8-webapp

The generated sources are not in jetty format. Not in itself a big deal, but when I try to run test the checkstyle plugin complains and fails.
So either remove the plugin or preserve the formatting.

Will be complicated for some parts to keep exact formatting.
So I will remove it. Sorry I was using a clean install so checkstyle do not complain same as Jenkins as checkstyle is executed before source generation.

@gregw still some issues for now with -config.jar so just use mvn test
