#1297: Upgraded to latest jgit.
fixes #1327 so we can provision cassandra containers using child containers (we should be able to add a docker configuration too really easily). As part of this fix I've enabled the use of overlayFolders containing static or mvel templates to override default configurations in tarballs which can include dynamically generated values (such as dynamically allocating ports and exposing them as environment variables)
