Create debian/.ubuntu package for sling launchpad standalone jar

I’m setting up a development env for a team to work on a sling asset manager app. I wanted to make the env setup simple so I put together a debian/ubuntu package for the org.apache.sling.launchpad-8-SNAPSHOT-standalone.jar.
It uses the jdeb maven plugin so it’s cross-platform. Here’s the patch on the off-chance it’s compatible with the upstream policies. If it needs tuning, let me know what it’s missing.

Comments from dev list:

• Do you mind creating a JIRA
• my preference would be to have this in contrib instead of the launchpad folder
