[ER1] SB 2 quickstarts have non-working readiness/liveness

We should switch to /actuator/health as described in https://www.baeldung.com/spring-boot-actuators by default, all Actuator endpoints are now placed under the /actuator path.

curl localhost:8080/actuator/health
{"status":"UP"}
sh-4.2$ curl localhost:8080/health
{"timestamp":"2019-10-04T06:52:14.495+0000","status":404,"error":"Not Found","message":"Not Found","path":"/health"}

Wrong probably in every SB2 quickstart - see https://github.com/jboss-fuse/application-templates/blob/application-templates-2.1.fuse-sb2-750009-redhat-00002/quickstarts/spring-boot-camel-template.json#L297 - iam not sure about FMP scenario, as i don't have functional FMP quickstart ATM.
