Add app-model and -lifecycle to platform api

Registered by Thomas Voß

The platform API currently lacks a well-defined app-model (what constitutes an application) and the definition of an app's lifecycle. Both parts need to be defined and implemented in the API to allow the overall system to be more clever in terms saving resources.

jdstrand, 2013-05-09> couple notes from the sprint - ted blogged about using upstart to manage apps here: http://gould.cx/ted/blog/Application_Centric_User_Experience. per stgraber, cgroup support could be integrated into upstart directly and until then could be setup in the pre-start stanza
