Added integration test rigging.

Addresses tracker issue: 56135376

The mechanism for spinning up fedora 3 in cargo was copied from Adam Soroka's example.  The vast majority of this commit is a fedora-home directory that appears in the src/test/resources/fedora-home directory which can be ignored.

The basic operation now is that:
1.  A fedora 3 war file is built
2.  Before integration tests that war file is loaded in cargo on port 8081 (which is scattered throughout several configuration files)
3.  The single sample integration test brings up a fedora 4 instance that includes configurations (packaged here) so that it federates over the fedora 3 repository.  You can see in the logs where it connects to fedora 3, and indeed lists the default objects.
