Sectioned view

[mestudd]

I want to create sectioned views with sections other than job lists. This branch adds the other sections of the view to the DSL.

I'm not a java/groovy dev, so I don't know if there's a better way of implementing the methods in SectionsContext.groovy. There's a lot of copy-paste in there.

Also, ./gradlew build fails at least 95% of the time with an error

:job-dsl-core:generateApiDocException in thread "main" java.lang.NoClassDefFoundError: org/fusesource/jansi/AnsiRenderWriter
but that's not related to the changes here.

This PR looks very good for a non-Java/Groovy dev. I pushed a few commits to reduce the copy&paste code and increased the test coverage.

./gradlew build never failed for me with that error. Can you post the output of ./gradlew --version so that I can see which OS and version of Java you are using?

Thanks.

I'm on Fedora 25 with default packages from dnf install
