backwards compatibility of client API

[ndegory]

Description

The Docker client API from tag v1.13.0-rc2 breaks the ImageList API when used with a Docker server below 1.25.

Steps to reproduce the issue:

1. Create a client with version 1.24: client := NewClient(socket, "1.24", nil, header))
2. Build an ImageListOptions object with a reference filter (replaces the MatchName property from previous versions of the API):

    filter := filters.NewArgs()
    filter.Add("reference", imageName)
    options := types.ImageListOptions{All: false, Filters: filter}

3. Use the ImageList object with these options: list, err := client.ImageList(ctx, options)
4. Test the client against a 1.12.3 Docker engine

Describe the results you received:

The Docker engine complains about an unknown filter:
Error response from daemon: Invalid filter 'reference'

Describe the results you expected:

The API should adapt (based on the version passed to NewClient) and provide the proper parameters to the server.
