Add async queryset for Django 4.1

[xncbf]

I have made things!

I added all of asynchronous queries created in django 4.1, including contains created in django 4.0.

This is ok as the first step, but please: take in mind that we also have special handling of .filter and other query set methods in out plugin.

This would need to be addressed as well.

damn I was just reviewing @sobolevn 😅 making a PR with these changes

this type is wrong - it doesn't take an iterable of type _T but a single instance of _T

https://docs.djangoproject.com/en/4.1/ref/models/querysets/#django.db.models.query.QuerySet.contains

Suggested change

	def contains(self, objs: Iterable[_T]) -> bool: ...
	async def acontains(self, objs: Iterable[_T]) -> bool: ...
	def contains(self, obj: _T) -> bool: ...
	async def acontains(self, obj: _T) -> bool: ...

Thanks for catching this! I never used async django, so my knowledge is limited: I was just checking that signatures are the same as regular methods.

Whilst modifying bulk_create let's also import the new Django 4.1 parameters.

https://docs.djangoproject.com/en/4.1/ref/models/querysets/#django.db.models.query.QuerySet.bulk_create

The update_conflicts, update_fields, and unique_fields parameters were added to support updating fields when a row insertion fails on conflict.

Suggested change

	def bulk_create(
	self, objs: Iterable[_T], batch_size: Optional[int] = ..., ignore_conflicts: bool = ...
	) -> List[_T]: ...
	async def abulk_create(
	self, objs: Iterable[_T], batch_size: Optional[int] = ..., ignore_conflicts: bool = ...
	) -> List[_T]: ...
	def bulk_create(
	self,
	objs: Iterable[_T],
	batch_size: Optional[int] = ...,
	ignore_conflicts: bool = ...,
	update_conflicts: bool = ...,
	update_fields: Optional[Collection[str]] = ...,
	unique_fields: Optional[Collection[str]] = ...,
	) -> List[_T]: ...
	async def abulk_create(
	self,
	objs: Iterable[_T],
	batch_size: Optional[int] = ...,
	ignore_conflicts: bool = ...,
	update_conflicts: bool = ...,
	update_fields: Optional[Collection[str]] = ...,
	unique_fields: Optional[Collection[str]] = ...,
	) -> List[_T]: ...
