build images with tag with https prefix never ends

[axel7083]

Reproduces

docker_client = docker.from_env()
docker_client .images.build(path="{my-path}", tag="https://dummy:latest", dockerfile="{dockerfile-path})

Using the debugger, we can see it loop on the _post request here:

docker-py/docker/api/build.py

Lines 264 to 271 in 84414e3

	response = self._post(
	u,
	data=context,
	params=params,
	headers=headers,
	stream=True,
	timeout=timeout,
	)

https://dummy:latest is not a valid image tag

Docker image tags can only contain lowercase and uppercase letters, digits, underscores, periods, and dashes. https://docs.docker.com/engine/reference/commandline/tag/

if you are trying to use custom registry, there's no need to add https prefix
