Description

AnalyzerFactory, added to the benchmark module in LUCENE-4723, is a factory of factories: as part of creating an analyzer, each analysis pipeline component's factory is invoked to create the component instances.

But unlike in Solr, where all analysis pipelines are explicitly specified per-field, benchmark algorithms have no way to specify per-field analyzers - an analyzer is always applied to all fields.

I propose a new task PerFieldAnalyzerFactoryTask, which would invoke PerFieldAnalyzerFactory: a factory of factories of factories.

(I've left "Wrapper" out of the name - it's already verging on overly long, and I don't think the meaning is compromised.)

I don't have an implementation yet - I wanted to see if people think there's a different/better way to do this.
