/**
 * Gets the Apache Solr field mappings.
 *
 * Field mappings define the various callbacks and Facet API keys associated
 * with field types, i.e. "integer", "date", etc. Mappings are gathered by
 * invoking hook_apachesolr_field_mappings().
 *
 * @param string $entity_type
 *   The machine name of the entity mappings are being collected for.
 *
 * @return array
 *   An associative array keyed by field type to an array of mappings
 *   containing:
 *   - dependency plugins: The Facet API dependency plugins associated with
 *     fields of this type.
 *   - map callback: The Facet API map callback that converts the raw values
 *     stored in the index to something human readable.
 *   - name callback:
 *   - hierarchy callback: The Facet API hierarchy processing callback for
 *     hierarchical facets.
 *   - indexing_callback: Callback used to retrieve values for indexing.
 *   - index_type: The Solr datatype associated with this field type.
 *   - facets: A boolean flagging whether facets are allowed for this field.
 *   - facet missing allowed: A boolean flagging whether the Facet API "missing
 *     facets" setting is supported by fields of this type.
 *   - facet mincount allowed: A boolean flagging whether the Facet API "minimum
 *     facet count" setting is supported by fields of this type.
 *   - multiple: A boolean flagging whether the field contains multiple values.
 *
