refactor the images & pdf apis out of the apiserver-core and into 2 new micro services (using Spring Boot)

create a new runner project that pulls images & pdf back in. So a single server can run all of the services too.
Move files out of core into cache micro service project. I will be renaming them from document* to cache* next

warning: broken build
check in a few deleted files
Remove the single monolithic project, everything is now in sub projects'
create a parent pom to centralize a lot of the dependencies
Add logging configuration, with logback.xml

get imageBlur and BoxBlur unit tests working with a new shared super class that starts up the server. And add new REST invoke tests.
