Support nested fields in existing filter types (elastic#49537)

* Add automatic support for nested fields in existing filter types

* Index pattern could be undefined

* add test for handleNestedFilter function

* remove console.log

* add tests for all "getFilterField" functions

* update migrateFilters to work on full filter objects so that it doesn't
have to worry about queries that have been wrapped with `nested`

* add test to ensure fromFilters auto wraps filters on nested fields

* Add smoke test for nested filter and move filter editor tests into
their own suite for easier running and debugging

* fix bad type change

* dedupe filterToQuery logic

* fix helper that wasn't doing what it said it did

* Convert test from pre-merge to jest

* Use new time range style
