Description

I can still see the resource warning from https://github.com/docker/docker-py/issues/1293 in some cases:

pytest.PytestUnraisableExceptionWarning: Exception ignored in: <socket.socket fd=-1, family=1, type=1, proto=0>

Traceback (most recent call last):
  File "<frozen _collections_abc>", line 435, in __subclasshook__
ResourceWarning: unclosed <socket.socket fd=41, family=1, type=1, proto=0, raddr=/var/run/docker.sock>

I use python 3.12 and docker-py 7.1.

I guess that the close method of BaseHTTPAdapter in docker/transport/basehttpadapter.py should call close on the pool rather than clear

Research direction

Start in docker/transport/basehttpadapter.py at BaseHTTPAdapter.close and inspect how the pool is currently cleaned up. Reproduce the ResourceWarning with Python 3.12 and docker-py 7.1, then verify that closing the adapter no longer leaves the Docker socket open.
