* Add first version of tests
From https://github.com/Tecnativa/docker-socket-proxy/pull/14
* Expand tests
* Add GH CI
* Apply suggestions
* Apply autopretty template + fix prettier
* Fix isort
* Apply autoprettier
* Fix VSCode settings
* Make tests run in parallel
* Build docker image before testing
* Update workspace settings
* Try multi-platform builds and push to ghcr.io
* Push to docker hub as well from ci
* Upgrade autopretty
* Update pyproject configurations

TT26468
* Provide initial conftest
* Improve tests
* Add python3 in image
* Remove POST rule from proxy
* Build image before testing and push at the end
Builds the image (in single arch) before testing
Loads the image into local docker (See https://github.com/docker/build-push-action#export-image-to-docker)
Rebuilds and pushes the final image in multi-arch at the end.
* Fix python path
* Remove build fixture from tests to see if image is built in CI
* Organize docker tests definition and document
* Restore fixture allowing usage for local testing
This reverts commit dc0b60e63f and allows using `--prebuild` CLI flag for pytest when doing local tests.
