>>> help(logging.handlers.HTTPHandler.mapLogRecord)
Help on function mapLogRecord in module logging.handlers:

mapLogRecord(self, record)
    Default implementation of mapping the log record into a dict
    that is sent as the CGI data. Overwrite in your class.      
    Contributed by Franz  Glasner.                              

Applied to your example:

import logging, logging.handlers, sys

class HTTPHandler(logging.handlers.HTTPHandler):
    wanted = ["levelname", "msg", "yadda"]

    def mapLogRecord(self, record):
        return {name: getattr(record, name, "#missing") for name in self.wanted}

logger = logging.getLogger('simple_example')
logger.setLevel(logging.DEBUG)
host = "localhost:9090"
url = "make_deployment_group"
http_handler = HTTPHandler(host, url, method='GET')
http_formatter = logging.Formatter('%(name)s - %(levelname)8s - %(message)s')
http_handler.setFormatter(http_formatter)
logger.addHandler(http_handler)
logger.warn('warn message')
