Title: - Compile capture processing to ruby code to avoid asking questions

about startup-time configuration every time there's an event.

This has a measured 6.3x perf improvement in grok filter performance.

It passes *almost* all the tests (66 examples, 4 failures). Each
failure is related to what I think is an uncommon edge case or
a feature that is going away eventually. The broken tests will be
fixed eventually.
