Client local repo

Add old Usergrid Java SDK client in a local Maven repo because our old repo (https://usergrid-maven.s3.amazonaws.com/dependencies) has gone away.

We can't use the newest Java SDK because it depends on the newest Jackson (2.3.1) and we cannot just drop it into the REST tests as it is a big API change. We REALLY need to upgrade the REST tests to use newer Jackson & Jersey, but that is a huge undertaking, so far now we have a temporary local repo.
