import_lab is not implemented in api wrapper

[ttafsir]

the lab import cli command is implemented to use api.import_lab, which does not exist.

@click.pass_context
def import_lab(ctx, folder, src):
    """
    Import lab into EVE-NG from ZIP archive
    """

    client = get_client(ctx)
    resp = client.api.import_lab(Path(src), folder)

Need to implement api.import_lab
