chore: Misc. logging changes (#797)

* Add .none ClientLogMode and make it defualt to make logging opt-in.

* Adjust logging levels for URL session HTTP client.

* Add public init and set default log level for initialize() method to .error.

* Fix SwiftLogger::log method to pass in the designated log level (self.level) to the underlying Logger::log method, instead of wrongly copying the log level passed into SwiftLogger::log.
