File is configured as expected when specifying api_ssl_* parameters using sensu-server-enteprise host.

[root@sensu-server ~]# cat /etc/sensu/conf.d/api.json

{
  "api": {
    "port": 4567,
    "host": "127.0.0.1",
    "bind": "0.0.0.0",
    "user": "admin",
    "password": "secret",
    "ssl_port": 4568,
    "ssl_keystore_file": "/etc/sensu/api.keystore",
    "ssl_keystore_password": "sensutest"
  }
}
