Phrase Suggester: Add collate option to PhraseSuggester
The newly added collate option will let the user provide a template query/filter which will be executed for every phrase suggestions generated to ensure that the suggestion matches at least one document for the filter/query. The user can also add routing preference `preference` to route the collate query/filter and additional `params` to inject into the collate template. Closes #3482
