[Mayan EDMS: 2183] feature request: in search API, return metadata of documents

[Tony Nys]

many metadata is stored on document level.
If we search documents with the API eg
" /api/dynamic_search/advanced/documents.Document/?_match_all=on&metadata__metadata_type__name=MY_ID&metadata__value=ABC"
it returns a result array without the metadata like below
Then for every document we need an extra api call to the metadata, so if a
user has 100 documents, it is 101 calls !
So please add an option to include document metadata in the search result
Funny enough this is already done in the UI page where the html contains
the docs + the metadata,
but it is not in the API
