Add configurations for the its-storyboard plugin:
1. Move java_home variable to a higher level module so it can be used
to install certificate on review-dev.o.o
2. Configure its-storyboard for review.o.o and review-dev.o.o
3. Associate review.o.o with storyboard.o.o and review-dev.o.o with
storyboard-dev.o.o
4. Import ssl certificate to java on review-dev.o.o so that the plugin
can POST updates to storyboard-dev.o.o using storyboard REST APIs.
5. Configure rules (or conditions) telling its-plugin to update
storyboard tasks status on specific gerrit change updates.
Gerrit change to storyboard task transition mapping:
change abandoned -> SB task set to 'todo'
change createed or change restored -> SB task set to 'review'
change merged -> SB task set to 'merged'
