Feature: Print Warning on Creation of Big Catalogs



This prints a warning during cvmfs_server publish when a catalog with more than x entries is committed (default value: 500,000). The threshold is (optionally) configurable in the server.conf file. It is only a warning, publishing succeeds regardlessly.

Additionally there is an integration test for this feature included.
