I am using CMRESHandler with ES 7.5.1. From ES 7, [type is deprecated](https://www.elastic.co/guide/en/elasticsearch/reference/current/removal-of-types.html) When CMRESHandler sends logs with bulk operation, `[types removal] Specifying types in bulk requests is deprecated.` warning is printed. Forcing to set es_doc_type is cause of this issue. [This line](https://github.com/cmanaha/python-elasticsearch-logger/blob/5e042bbe42b75ebd4c435b3b054ef44a3060c1a3/cmreslogging/handlers.py#L295) may need to be deleted.
