yarl (0.8.1) not compatible and not able to add http headers

[zpoint]

yarl (0.8.1) aio-libs/yarl#9

File "/usr/local/lib/python3.5/dist-packages/aioes/connection.py", line 41, in perform_request
    url = self._base_url.with_path(url)
AttributeError: 'URL' object has no attribute 'with_path'

I update aiohttp to 2.0.3 slove the "with_path" problem

And
I am not able to add http headers when I perform http request in es operation
I want to pass header as argument when instantiate the es client

headers = {"Host": u"***", "key": "***"}
es = Elasticsearch(['localhost:8888'], headers=headers)

TypeError: __init__() got an unexpected keyword argument 'headers'

with elasticsearch==5.1.0, I can do that
Now
I need to reserve header argument in connection.py->Connection->perform_request, and reserve for every method/class using it

aioes delete_by_query use something like this DELETE twitter/_query

not compatible with latest document

https://www.elastic.co/guide/en/elasticsearch/reference/current/docs-delete-by-query.html

POST twitter/_delete_by_query
