feat(post): deis 0.12 release

Still a WIP, especially the title. Please post feedback here and I'll update. ping @gabrtv @bacongobbler @JoshuaSchnell @carmstrong @smothiki.
We should use "application" as it's more formal. We should use "application life cycle information" because the feature shows application lifecycle logs which aren't tied to releases like scaling, adding domains, etc.
