DevStudio build results should contain file with additional information

Current implementation hardcode DevStudio version/url into Platform-Installer. Would be good to be able to get this info form download location in form of content.json file:

{ 
"name": "Red Hat Developer Studio",
"description": "DevStudio 10.0.0.Alpha2 Nightly Build",
"fullVersion": "10.0.0.Alpha2-XXXXXXXXXXXXX-B0001",
"installer": "https//downloadhost.com/devstudio-10.0.0.Alpha2-XXXXXXXXXXX-B0001-installer.jar"
}

Full URL is required to avoid download interruptions, when new version of DevStudio is uploaded and files available from stable URL is overwritten with latest nightly build. In this case a client downloaded content.json has direct link to installer jar from specific nightly location, which is usually kept for several days.
