Looker/Lookml ingestion doesn't support view inheritance

[pedro-iatzky]

Describe the bug Looker/Lookml ingestion does not handle inheritance correctly. When I extract a view that is extending another the child view does not show the parent dimensions/measures.

To Reproduce Steps to reproduce the behavior:

1. Create the following file in Lookml

explore: datahub_test {
  view_name: child_view
}

view: parent_view {
  sql_table_name: `dataset.table` ;;

  dimension: id {
    primary_key: yes
    type: string
    sql: ${TABLE}.id ;;
  }

  dimension: parent_dimension_1 {
    type: string
    sql: ${TABLE}.parent_dimension_1 ;;
  }

  measure: parent_count {
    type: count
  }
}

view: child_view {
  extends: [parent_view]

  dimension: child_dimension_1 {
    type: string
    sql: ${TABLE}.child_dimension_1 ;;
  }
}

2. Run Lookml & Looker ingestion

Expected behavior I would expect to see two views extracted. The parent, and the child. Also, the child_view should show the dimensions/measures inherited from parent

This seems like a bug in get_including_extends - for "list" fields like dimension/measure/etc, we need to merge with parent views instead of only fetching the value for the child field
