website: mention node name for "agent/force-leave" HTTP endpoint (#4542)
* Adjust documentation for agent/force-leave endpoint
A node must be specified when calling agent/force-leave.
See:
- https://github.com/hashicorp/consul/blob/master/agent/http_oss.go#L25
- https://github.com/hashicorp/consul/blob/master/agent/agent_endpoint.go#L323
- https://github.com/hashicorp/consul/blob/master/agent/agent.go#L1442
However, the documentation does not specify it.
Note that Consul returns "301 Moved Permanently v1/agent/force-leave/" when sending PUT request on "v1/agent/force-leave".
* Switch from node id to node name
