Currently Solr backend field names generated for Content fields consist of ContentType identifier, FieldDefinition identifier, name of particular indexed field for the field type and type suffix.

ContentType identifier is redundant as the Content can "instantiate" only a single ContentType.
Also, removing ContentType identifier would be beneficial for relevancy calculation as the same field names could exist across ContentTypes (eg. title_value_s instead of article_title_value_s and blogpost_title_value_s)
