Refactored HttpAsyncHook to easily support session based operations.

Instead of having to do this:

    @task(
        retries=3,
        retry_delay=timedelta(seconds=60),
        show_return_value_in_logs=True,
    )
    async def fetch_forms(project_id: int):
        from aiohttp import ClientSession
        from functools import partial

        from airflow.providers.http.hooks.http import HttpAsyncHook

        auth_type = partial(BearerTokenAuth, url="https://localhost/v1/sessions")
        hook = HttpAsyncHook(http_conn_id="http_conn_id", auth_type=auth_type, method="GET")

        async with ClientSession() as session:
            response = await hook.run(
                session=session,
                endpoint=f"v1/projects/{project_id}/forms",
            )
            return await response.json()

You will be able to do this instead:

    @task(
        retries=3,
        retry_delay=timedelta(seconds=60),
        show_return_value_in_logs=True,
    )
    async def fetch_forms(project_id: int):
        from functools import partial

        from airflow.providers.http.hooks.http import HttpAsyncHook

        auth_type = partial(
            BearerTokenAuth, url="https://localhost/v1/sessions"
        )
        hook = HttpAsyncHook(
            http_conn_id="http.odk.acc", auth_type=auth_type, method="GET"
        )

        async with hook.session() as session:
            response = await session.run(
                endpoint=f"v1/projects/{project_id}/forms",
            )
            return await response.json()
