Reference BP: https://blueprints.launchpad.net/solum/+spec/specify-lang-pack

Proposed Implementation 1:
--------------------------------------

1) Get available language packs:

GET /v1/language-packs

Return:
[
   {language-pack:org.openstack.java.Java-1.6},
   {language-pack:org.openstack.python.python3.3}
]

2) Specify language pack to be used as part of the application plan:

POST /v1/assemblies

{
  camp_version: CAMP 1.1
  artifacts: {
     artifact_type: org.openstack.python.pyc
     content: { href: helloworld }
     requirements:
        requirement_type: org.openstack.interpreted_by
        fulfillment: id:py33
   }
   services: {
      id:py33
      characteristics:
         characteristic_type: org.openstack.python.python3.3   <--- Specify existing language pack 
    }
}

Proposed Implementation 2 for GET:
--------------------------------------------------

If we consider language packs as being a 'component', then the GET call would need to change to
something like:

GET /v1/components/

Return:
[ 
   { name: 'Python language pack'
     type:language-pack:org.openstack.python.python3.3     <--- Type identifies that this component is a language pack
     description: 'This is Python language pack',
     tags: ['Python 3.3 Language Pack']
    },
     { name: 'Java language pack'
     type:language-pack:org.openstack.java.Java-1.6
     description: 'This is Java language pack',
     tags: ['Java 1.6 Language Pack']
    }
]
