public S withPlugins(MountableFile plugins) {
        return withCopyFileToContainer(plugins, "/var/lib/neo4j/plugins/");
    }
Adds plugins to the given directory to the container. If {@code plugins} denotes a directory, than all of that
directory is mapped to Neo4j's plugins. Otherwise, single resources are copied over.
<br>
If you want to map your plugins into the container instead of copying them, please use {@code #withClasspathResourceMapping},
but this will only work when your test does not run in a container itself.

@param plugins
@return This container.
