Add quarkus:dev option for running the examples

[tplevko]

Based on comment - adding the option to run the examples using:

mvn clean compile quarkus:dev

@lburgazzoli there seems to be a problem with the java example, which doesn't seem to run using the above mentioned command - there seems to be a problem with classloading, the problem is:

2021-04-16 13:51:22,023 ERROR [org.apa.cam.qua.mai.CamelMainRuntime] (Quarkus Main Thread) Failed to start application: org.apache.camel.RuntimeCamelException: org.joor.ReflectException: Compilation error: /MyRoutes.java:17: error: package org.apache.camel.builder does not exist
import org.apache.camel.builder.RouteBuilder;
                               ^
/MyRoutes.java:19: error: cannot find symbol
public class MyRoutes extends RouteBuilder {
                              ^
  symbol: class RouteBuilder
2 errors

I couldn't find the cause of this issue, I can however remove the option from this example, in case there is no easy solution.

Release Note

NONE

Is this change required ?

[tplevko]

Not necessarily. It is related to the PR I made previously and it effectively reverts the change I introduced, generating uber-jar instead of the fast-jar:

java -jar target/quarkus-app/quarkus-run.jar
java -jar target/camel-k-runtime-example-cron-runner.jar

In case this is undesired, I will remove it from the PR (Apparently I should have separated it in 2 commits in the first place.)

[lburgazzoli]

I'd prefer to use the fast-jar mode as it is the mode we use on camel-k (unless there are known issues)

[tplevko]

Understood, will remove this particular type of changes

[tplevko]

Should be back to the previous fast-jar usage
