Removes all the logger::on_xxx functions Removes the Logger template parameter to async_run Adds a logger constructor that allows passing a std::function to customize logging behavior Adds constructors to connection and basic_connection taking a logger Deprecates config::logger_prefix Deprecates the async_run overload taking a logger parameter Deprecates the basic_connection::async_run overload not taking any config object Deprecates the basic_connection::next_layer_type typedef Makes the default log level logger::info Makes the logging thread-safe Cleans up deprecated functionality from examples Adds docs on logging Adds an example on how to integrate spdlog into Boost.Redis logging close #213
