+1, with the following caveats:
1. Since parser.configure() takes a (Map<String, Object> parserConfig)
argument, so should parser.configurationChanged(), rather than a
sensorParserConfig. I would also name it parser.configurationUpdate() rather
than parser.configurationChanged(), but that's obviously minor.
2. Very nice hooking into updateConfig(), BUT we can't call
parser.configurationUpdate() asynchronously. Weird things might happen if it's
in the middle of a message. Instead, please set a local flag asynchronously in
ParserBolt, then at each message check-and-clear the flag, and conditionally
call parser.configurationUpdate() before parser.parseOptional().
