+Set `verbose` to `true` to enable verbose mode that logs a summary of every HTTP response. Verbose mode can be disabled by calling `disableVerboseMode` method or enabled by `enableVerboseMode` method. Verbose mode also supports `bleached` mode that disables extra colors in req/res summary. To enable `bleached` verbose mode, pass `verbose` equal to `bleached` while instantiating an instance of `RequestClient` or to `setVerboseMode` method. Verbose mode can also be enabled/disabled by `startComputeJob` method.

 * `debug` - if `true` then SAS Logs and extra debug information is returned.
