podman.sock network mode compatibility when creating container

[panda2134]

Issue Description

podman.sock seems to be converting default network names to bridge to mimic docker behavior. Even when podman network ls shows the default network name as podman, a RESTful API request to /networks/ still returns the network name as bridge.

This behavior is not consistent with /containers/create. When the network name "bridge" is used in "NetworkingConfig.EndpointsConfig", podman returns 500 saying that "container create: unable to find network with name or ID bridge: network not found"

Steps to reproduce the issue

Steps to reproduce the issue

Run the following script after enabling podman.sock:

podman pull alpine
cat >/tmp/1.json <<EOF
{
    "Image": "alpine",
    "HostConfig": {
        "NetworkMode": "bridge"
    },
    "NetworkingConfig": {
        "EndpointsConfig": {
            "bridge": {
                "Aliases": []
            }
        }
    }
}
EOF
curl --unix-socket $XDG_RUNTIME_DIR/podman/podman.sock -H 'content-type: application/json' -d @/tmp/1.json http://localhost/containers/create

Describe the results you received

Error: {"cause":"network not found","message":"container create: unable to find network with name or ID bridge: network not found","response":500}

Describe the results you expected

No errors.

@Luap99 Any ideas on this one?

Translate the name the same same way it done in the network endpoints
