Description

STR:

1. Create cluster via blueprints
2. Add a new node to one of the host groups specifying host_name in the request body according to the "multiple hosts" example in wiki

Expected result: host is added
Actual result: request is rejected with "Must specify either host_name or host_count" error

$ curl -X POST -d '[ { "blueprint": "blue", "host_group": "node", "host_name": "c6402.ambari.apache.org" } ]' http://c6401.ambari.apache.org:8080/api/v1/clusters/TEST/hosts
HTTP/1.1 400 Bad Request

Similar request with host name under Hosts/host_name is accepted:

$ curl -X POST -d '[ { "blueprint": "blue", "host_group": "node", "Hosts": { "host_name": "c6403.ambari.apache.org" } } ]' http://c6401.ambari.apache.org:8080/api/v1/clusters/TEST/hosts
HTTP/1.1 202 Accepted

Also, request with host name specified path is accepted:

$ curl -X POST -d '[ { "blueprint": "blue", "host_group": "node" } ]' http://c6401.ambari.apache.org:8080/api/v1/clusters/TEST/hosts/c6404.ambari.apache.org
HTTP/1.1 202 Accepted

All three requests work fine in Ambari 2.5.2.
