Adrien Grand c50c5a52d5 Rework norms parameters for 5.0. #16987
Changes:
 - no more option to configure eager/lazy loading of the norms (useless now
   that orms are disk-based)
 - only the `string`, `text` and `keyword` fields support the `norms` setting
 - the `norms` setting takes a boolean that decides whether norms should be
   stored in the index but old options are still supported to give users time
   to upgrade
 - setting a `boost` no longer implicitely enables norms (for new indices only,
   this is still needed for old indices)
