@joeyAghion => Bump scala-common-enrich to 0.2.2-SNAPSHOT

This PR shifts the common-enrich library, which was moved over to artsy sonatype in: https://github.com/artsy/snowplow/pull/2 to be pulled from that repository, as well as getting the latest version.

@joeyAghion want to deploy this app (scala-kinesis-enrich) as followup?
