* refactor: moved cli flags to pkg cli/flag * testh: add OptLongDB for long-running tests * implement 'sq config dir' * legacy dir migration: probably a bad idea * cleanup * Refactored SQ_CONFIG and --config * added yaml writer * Dialing in tests * YAML output for 'sq driver ls' * Significant refactoring of config * Minor test for ioz * Rename source.Set to source.Collection * Cleaning up references to source.Set
