Jackson with MySQL connector CVE - partial update

More information here: FasterXML/jackson-databind#2326

I've changed the easy ones. Also some of the projects where a little more exclusion/inclusion was needed. What is left are the ones with the most effort required.

• Java/jooby2 - even RC3 doesn't have Jackson 2.9.9. Probably the declaration as child POM should be removed. Than exclude and import the correct version of the dependencies;
• Java/ratpack - Gradle build;
• Java/proteus - around 6 Jackson dependencies;
• Java/spring;
• Java/spring-webflux;
• Clojure/http-kit;
• Clojure/compojure;
• Clojure/aleph;
• probably I've missed some.

I don't plan to work on them. It will be too much effort for me.
