HTTP SSL Verification flag not passed to SpooledSegment class which fails HTTP requests

[JustinObanor]

Expected behavior

SSL Verification flag set to False when initialising a connection to Trino is used in HTTP requests for spooled segments.

Actual behavior

SSL Verification flag set to False when initialising a connection to Trino is not passed to HTTP requests for spooled segments and therefore fails with HTTP SSL errors

Steps To Reproduce

Configure Trino spooling manager properties

[trino@trino-0 /]$ cat /etc/trino/spooling-manager.properties
spooling-manager.name=filesystem
fs.gcs.enabled=true
fs.location=gs://xyz-base-trino-1/spooling-segments/product

Configure Trino to use Spooling

[trino@trino-0 /]$ cat /etc/trino/config.properties
...TRUNCATED...
protocol.spooling.enabled=true
protocol.spooling.shared-secret-key=<secret-key>
protocol.spooling.retrieval-mode=COORDINATOR_STORAGE_REDIRECT

Initialise a connection to Trino

from trino.dbapi import connect
from xyzplatform.sql import xyzTrinoAuth
import logging
import warnings
import requests

logging.basicConfig()
logging.getLogger().setLevel(logging.DEBUG)

session = requests.Session()
session.verify = False

conn = connect(
    http_scheme="https",
    host="trino.trino",
    port=443,
    catalog="hive",
    schema="tpcds_europe_west1_1000",
    verify=False,
    auth=xyzTrinoAuth(),
    encoding="json+zstd",
    http_session=session,
)

Make a request

warnings.filterwarnings(
    "ignore", message=f"Unverified HTTPS request is being made to host https"
    )

cur = conn.cursor()
cur.execute("SELECT * FROM hive.tpcds_europe_west1_1000.date_dim")
rows = cur.fetchall()

With a debug session, we see Verify is False, which is correct

But right before we make a request to send_spooling_segment, Verify is True, which wasn't expected
