Fleet Elasticsearch CA trusted fingerprint

Hi @nchaulet

thanks for that. I tried to use your code but got some errors. In my case i had to add --insecure and -u elastic:password
After that I still get an error:

curl -u elastic:password \
  --insecure \
  --request POST \
  --url https://127.0.0.1:5601/api/fleet/outputs/fleet-default-output \
  --header 'kbn-xsrf: true' \
  --data '{
	"name": "default",
	"type": "elasticsearch",
	"hosts": [
		"https://localhost:9200"
	],
	"is_default": true,
	"is_default_monitoring": true,
	"config_yaml": "#test",
	"ca_trusted_fingerprint": "87:29:43:88:E1.....B5:70:E1:55:91:63"
}'
curl: (35) error:1408F10B:SSL routines:ssl3_get_record:wrong version number

Also if I use the webserver instead of the kibana service itself with --url https://localhost/api/fleet/outputs/fleet-default-output \ I am getting the following:

{"statusCode":404,"error":"Not Found","message":"Not Found"}

Not sure whats wrong in any case.

Best Regards
