This commit applies `server.jetty.*` configuration properties
to Jetty when configured as a reactive web server.
It also removes some infrastructure support for Jetty 8, which
is not supported anymore in Spring Boot 2.0 (partial fix for
gh-11504).
See gh-11500
This commit applies most `server.tomcat.*` configuration
properties to Tomcat when set up as a reactive web server.
Some Servlet-specific properties are not applied:
* server.tomcat.additional-tld-skip-patterns
* server.tomcat.redirect-context-root
* server.tomcat.use-relative-redirects
Fixes gh-11334
