* TestGetLicenseFileFromDisk: avoid using fileutils.FindConfigFile * config: abstract config-related file access, extend memory store * simplify config validate to avoid file knowledge * fix relative file tests * cluster: fix ConfigChanged event The old and new configurations were swapped when notifying the enterprise code of configuration changes, creating needless instability in propagating config updates across a cluster. * config/database: ignore duplicates * test cleanup * remove unnecessary Save() in test
