Connecting to remote docker host over ssh is broken

[rajiv-k]

As reported by @whobutsb:

I was testing out this new functionality. Is honoring the docker context only available for http connections? Am I able to use ssh connections? When I changed my docker context and ran lazydocker I wasn't able to connect. Here is the inspection on my docker context:

> docker context inspect uj-staging
[
    {
        "Name": "uj-staging",
        "Metadata": {},
        "Endpoints": {
            "docker": {
                "Host": "ssh://uj-staging",
                "SkipTLSVerify": false
            }
        },
    }
]
