Lee Hinman 2c289fb538 Add the ability to retrieve fields from field data
Adds a new FetchSubPhase, FieldDataFieldsFetchSubPhase, which loads the
field data cache for a field and returns an array of values for the
field.

Also removes `doc['<field>']` and `_source.<field>` workaround no longer
needed in field name resolving.

Closes #4492
