You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: http.rb
    path of file: ./repos/dd-trace-rb/lib/datadog/tracing/transport
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

require 'uri'

require
    
        def default_hostname(logger: Datadog.logger)
          logger.warn(
            'Deprecated for removal: Using #default_hostname for configuration is deprecated and will ' \
              'be removed on a future ddtrace release.'
          )

          DO_NOT_USE_ENVIRONMENT_AGENT_SETTINGS.hostname
        end
