Fix Generator repository storage version check for incoming Cluster
Closes #320 (closed)
Details per issue above: when Gitaly Cluster is set up, the target environment has two repo storages, one unused one named default
and another called storage-1
(Gitaly Cluster). We need to update repository storage version check to always check the environment ignoring storage count.
Additional small change: use new small project tarball that was added to performance-data
