Make requets.Session injectable

[altescy]

Make requets.Session injectable to configure remote server connections.
In this PR, the session option is added to QueueryClient.__init__ to support retries, etc. as follows:

from requests import Session
from requests.adapters import HTTPAdapter
from urllib3.util.retry import Retry

from queuery_client import QueueryClient

session = Session()
session.mount(
    "https://",
    HTTPAdapter(
        max_retries=Retry(
            connect=2,
            total=5,
            backoff_factor=1,
            status_forcelist=[500, 502, 503, 504],
        ),
    ),
)

client = QueueryClient(session=session)

The given session is passed to the Response object and is used not only to connect to the Queuery server, but also to access unloaded files. Thus, you can write different configurations for the Queuery server / S3, etc.

session.mount(
    "https://queuery.example.com",
    HTTPAdapter(max_retries=Retry(total=3)),
)
session.mount(
    "https://your-bucket.s3.ap-northeast-1.amazonaws.com",
    HTTPAdapter(max_retries=Retry(connect=3, total=5)),
)
