Review Comment:
   I'm not sure the current vendoring workflow is suitable for my situation. 
I'm the author of these two files, but they are hosted in two places: ydb 
github repo and airflow github repo. In ydb repo we have integration tests 
where we ensure protocol between client and YandexQuery (YQ) backend. These 
tests cannot be moved to airflow repo. So the source of truth is ydb repo. But 
this client logic is required for airflow operator and there is no pypi package 
which contains this code. So I decided just to copy it and add some tests with 
hardcoded YQ backend reponses. I would suggest to fix original code first and 
then backport it to airflow repo. I can rework these files as if they where 
created just inside airflow without link to ydb repo, but I wouldn't recommend 
to maintain them separately from ydb repo.
   YDB repo has Apache 2 licence, therefore it is safe to copy files from ydb 
repo completely or partially to another repository.
   We have amazing plan to improve our YQ backend so that it would pretend to 
be a YDB cluster. That means that we can use existing YDB python SDK ( 
https://github.com/ydb-platform/ydb-python-sdk ) to access YQ backend and these 
two files with http client logic could be removed afterwards. But improving YQ 
backend is not easy^ we would spent several months to make it.
