Currently only the GrokParser wants to see the sensorParserConfig, right?
Then this patch could be significantly simplified, if desired, by providing
both one and two-argument polymorphisms of the parse() method. BasicParser
would provide an overridable implementation of the two-argument form as a
trivial call to the one-argument form. GrokParser can implement the
one-argument form with either an exception throw, or a two-argument call with
"current parserConfig" (which would need to be saved from the
GrokParser:configure() call). Of course the clients of GrokParser still need
to be modified, but all the non-Grok parsers and their unit tests no longer
need to change. I think that eliminates 20 of the 38 files in this patch.
