Similar to the Java API, it would be nice if it were possible to set this custom prefix so that we could pull images from our local docker registry.

This is also mentioned in another issue:

Same issue here. The testcontainers-python is missing support for TESTCONTAINERS_HUB_IMAGE_NAME_PREFIX

Because of this we cannot pull from Artifactory and get rate limit from dockerhub

java and node implementation that we also use support the env var
