Add standard set of run stages.

Many modules I'm working on need a standard but
relatively granular location in the catalog.  For example,
any module that configures the packaging system should
run "early"

Add the following stages which have inter-dependencies
in the top to bottom order listed:

 * setup
 * deploy
 * runtime
 * setup_infra
 * deploy_infra
 * main
 * setup_app
 * deploy_app
