Sebastiaan van Stijn 462d0ff5aa client: Client.doRequest: simplify permission check and unwrap error
Previously, we were using os.IsPermission, which doesn't unwrap errors;
change to use `errors.Is` to detect permission errors, and unwrap the
error to remove information about the request, which is irrelevant if
we weren't able to connect in the first place.

Also tweak the error slightly to not assume "docker socket", instead
mentioning "docker API".

Before this;

    permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Get "http://%2Fvar%2Frun%2Fdocker.sock/v1.51/version": dial unix /var/run/docker.sock: connect: permission denied

With this patch applied:

    permission denied while trying to connect to the docker API at unix:///var/run/docker.sock: dial unix /var/run/docker.sock: connect: permission denied

Go client for the Docker Engine API

The docker command uses this package to communicate with the daemon. It can also be used by your own Go applications to do anything the command-line interface does running containers, pulling images, managing swarms, etc.

For example, to list all containers (the equivalent of docker ps --all):

package main

import (
	"context"
	"fmt"

	"github.com/docker/docker/api/types/container"
	"github.com/docker/docker/client"
)

func main() {
	apiClient, err := client.NewClientWithOpts(client.FromEnv)
	if err != nil {
		panic(err)
	}
	defer apiClient.Close()

	containers, err := apiClient.ContainerList(context.Background(), container.ListOptions{All: true})
	if err != nil {
		panic(err)
	}

	for _, ctr := range containers {
		fmt.Printf("%s %s (status: %s)\n", ctr.ID, ctr.Image, ctr.Status)
	}
}
