Is there any way I can perform a graceful leave and shutdown for consul agent using this library that performs the following action?

$ curl \
    --request PUT \
    http://127.0.0.1:8500/v1/agent/leave

Also, when I tried to use force_leave in version 1.1.0, the server responded with 405 because that version still uses get method instead of put (here). Is there any upcoming release that will include this fix?
