Solum-R2: Language Pack framework
Solum will implement a framework for self-serve pluggability of language/runtime stacks (note: evaluate Heroku buildpack compatibility)

Solum-R2.1 Pluggable language packs (P1)
As a platform developer, I want to be able to plug-in support for my desired language/run time stack into the platform (in the form of language packs), without having to change the core platform code.

Solum-R2.2 Automatic selection of language packs (P1)
As an application developer, I can push my code to the platform, and have the platform automatically select the appropriate language pack to build+ deploy my application.

Solum-R2.3 Combine language packs (P2)
As a platform developer, I want to be able to combine/chain language packs to create new top level packs (for example, combine the basic Java pack with the "Setup Tomcat" pack to create a Tomcat container)

Solum-R2.4 Specify language pack (P2)
As an application developer, I can explicitly specify the language pack that the platform would use to deploy my code, instead of using the default language pack.
