I was nuts when I wrote init. Making it all one giant program
in a single class was simply insane. Instead we break it down
into many smaller classes and use Guice to manage the creation,
dependency injection, and control flow.
Since init knew about most of the Files under the $site_path we put
them all into a single immutable class called SitePaths and replace
all references to these throughout the code base to use SitePaths
and these well defined constants.
init can now also import GerritServer.properties into the newer
style gerrit.config and secure.config. This ensure the database
settings are setup with the current defaults
