I did consider adding a type to be able to index histogram values and counts. Thoughts?

The docs (https://www.elastic.co/guide/en/elasticsearch/reference/7.x/histogram.html) indicate the format for indexing is quite simple:

PUT my_index/_doc/1
{
  "my_text" : "histogram_1",
  "my_histogram" : {
      "values" : [0.1, 0.2, 0.3, 0.4, 0.5], 
      "counts" : [3, 7, 23, 12, 6] 
   }
}

I think a type to index this is probably worth it and quite simple to implement?

• Test failures are fixed in 7.x upstream

A type used for indexing would be good, however we would also need to make sure it works well with Json.NET as the source serializer.

It being a simple type was my reason to not implement it 😄 Could add one in a follow up PR?
