Alan Woodward c6b31162ba Refactor percolator's QueryAnalyzer to use QueryVisitors ... Lucene now allows us to explore the structure of a query using QueryVisitors, delegating the knowledge of how to recurse through and collect terms to the query implementations themselves. The percolator currently has a home-grown external version of this API to construct sets of matching terms that must be present in a document in order for it to possibly match the query. This commit removes the home-grown implementation in favour of one using QueryVisitor. This has the added benefit of making interval queries available for percolator pre-filtering. Due to a bug in multi-term intervals (LUCENE-9050) it also includes a clone of some of the lucene intervals logic, that can be removed once upstream has been fixed.
