cli-plugins/plugin: Run: allow customizing the CLI

Currently, the plugin.Run command constructs the DockerCli using
the default options, assuming plugins run with all the same options
as the CLI itself; to customize the CLI there's a "Apply" option,
but this means mutating the CLI after it's already constructed, which
is not ideal.

This patch adds a variadic ops argument to allow CLI plugins to pass
custom options to use for the CLI, so that there's no need to mutate
its config in most cases.
