Add support for passing csvDelimiter query parameter to the PUT and POST /indexes/:indexUid/documents with content-type text/csv (example of the real method names: updateDocuments, addDocuments).

Also, a new error code is introduced, invalid_document_csv_delimiter. Pay attention to the strongly typed languages.

TODO:

• Add the new argument to the csv document handler methods.
• Add tests
