Missing protocol scheme in docker_host. When I use a lot of certificaties

Missing protocol scheme in docker_host.

Hello,

Background

I have a lot of servers, which I need to manage with cert in different dir.

This method: def _docker_machine_ssl_context()
just allow get CERT only from this os.environ.get("DOCKER_CERT_PATH", None) path.

So when I want to use many cert from different directory I prepare custom ssl.SSLContext with path, which I need.

Issue

But here some issue with this part of code:

if _rx_tcp_schemes.search(docker_host):
    if os.environ.get("DOCKER_TLS_VERIFY", "0") == "1":
        if ssl_context is None:
            ssl_context = self._docker_machine_ssl_context()
            docker_host = _rx_tcp_schemes.sub("https://", docker_host)

_rx_tcp_schemes check for http or tcp, if I set up https, I will get ValueError("Missing protocol scheme in docker_host.") error.
Because there are not https scheme in if else statement.
If I use http instead(to pass this if statement), when will create connection to docker, I will get: used http instead https scheme

So there are no way to do custom ssl.SSLContext with https scheme rn.
In my problem, I just changed indent of one line.

if _rx_tcp_schemes.search(docker_host):
    if os.environ.get("DOCKER_TLS_VERIFY", "0") == "1":
        if ssl_context is None:
            ssl_context = self._docker_machine_ssl_context()
        docker_host = _rx_tcp_schemes.sub("https://", docker_host) #this one

May be it will be helpfull, Thanks!
