https://github.com/apache/camel/pull/2353
camel service registry
This PR is the initial work to ease the process to expose routes as
services [CAMEL-10793](https://issues.apache.org/jira/browse/CAMEL-10793).
A simple example is:
```java
from("service:my-service:undertow:http://0.0.0.0:8080/the/context/path";)
.log("Route ${routeId} has been invoked");
```
As undertow component, supports service registration, this endpoint will be
registered to a given Service Registry (we now have a binding for consul,
zookeeper and spring-cloud) as `my-service` along with some metadata such as
the protocol and the context path. This allow to invoke the service on another
jvm instance by name, like:
```java
from("direct:call")
.serviceCall("my-service")
```
**NOTE**: The implementation is not yet complete so you still need to do
some manual configuration and the number of supported component that support
service registration is limited to those extending `camel-http-common` and
`undertow` .
**NOTE**: integration with spring-cloud is not as easy as it should be so I
had to introduce two new modules: camel-spring-cloud-zookeeper and
camel-spring-cloud-consul.
Any feedback would be really appreciated.

> camel cloud: expose routes as a service
> ---------------------------------------
>
> Key: CAMEL-10793
> URL: https://issues.apache.org/jira/browse/CAMEL-10793
> Project: Camel
> Issue Type: New Feature
> Components: camel-core
> Reporter: Luca Burgazzoli
> Assignee: Luca Burgazzoli
> Priority: Minor
> Labels: cloud
> Fix For: 2.22.0
>
>
> As today we have a ServiceCall EIP that makes it easy to call external
> services in a cloud environment leveraging external service registry such as
> kubernetes, consul, etcd, spring-cloud & co so It could make sense to add a
> way for a route to register itself in such registries and be available as a
> service for other to consume.
> Something like:
> {code:java}
> // programmatic config
> from("jetty:http://0.0.0.0:8001/service1";)
> .serviceRegistry()
> .name("service-1")
> .host("....")
> .port(8001)
> .meta("camel.protocol", "http")
> .meta("camel.component", "jetty")
> .meta("camel.context.path", "/service1")
> .end()
> .to("direct:service-1")
> // Inherit from a global config and eventually override it
> from("jetty:http://0.0.0.0:8002/service2";)
> .serviceRegistry("service-2")
> .configRef("service-registry-conf")
> .port(8002)
> .to("direct:service-2")
> // Smart auto configuration
> // i.e. if the endpoint implements DiscoverableService
> from("jetty:http://0.0.0.0:8003/service3";)
> .serviceRegistry("service-3")
> .to("direct:service-3")
> {code}
> Beside making camel play better in cloud environment, you can use the
> service call to connect camel based micro services with minimal configuration
> as the registration may provide some additional meta data that the service
> call can use for auto-configuration (of course not all the registries can do
> it).
> The future Health API/Service may then also be configured to remove or
> invalidate the service if the route is reported as not healthy.
