Create /graph/operations/all endpoint

[t92549]

Describe the new feature you'd like
A /graph/operations/all endpoint should be added to return all operations on the classpath.

Why do you want this feature?
The /graph/operations/details/all was added to return the details of all operations on the classpath, but sometimes users don't want details, just the name of the operations.

Additional context
It would be nice if the endpoint returned them sorted alphabetically (see #2775).
For implementation, see the /graph/operations/details/all endpoint.

There are Maven profiles in the spring-rest and road-traffic-demo modules. These allow the endpoints (Spring REST or .war with Tomcat) be run locally for testing.
For Spring run mvn compile -Pdemo -pl :spring-rest then go to http://localhost:8080/rest/ and you will see the Swagger site.
For .war run mvn integration-test -Proad-traffic-demo -pl :road-traffic-demo and then go to http://localhost:8080/rest/ and you will see the Swagger site.

The road-traffic-demo also includes some data.

Note that as with #2690 this is only for spring-rest.

Closed by #3011. However this did not include sorting. Although sorting was part of the original issue above, the potential for sorting can instead be discussed in the issue specific to it (#2775).
