fix(trait): remove imageWasKit

As discussed in apache#5399 we need to clarify the intent of each IntegrationKit types.

* removal of imageWasKit
* usage of external IntegrationKit when we are certain that the image comes from an IK
* usage of syntetic IntegrationKit when the image are coming from any container image
* rework of promote command to clone an external IntegrationKit beside the Integration and use it accordingly.

Closes apache#5408

 Camel K can run any runtime available in Apache Camel. However, this is possible only when the Camel application was previously built and packaged into a container image. Also, if you run through this option, some of the features offered by the operator may not be available. For example, you won't be able to discover Camel capabilities because the source is not available to the operator but embedded in the container image.

 The step above is a very quick way to create a basic Camel application in any of the available runtime. Let's imagine we've done this for Camel Main or we have already a Camel application as a Maven project. As the build part is something we want to take care on our own, we create a pipeline to build, containerize and push the container to a registry (see as a reference https://github.com/tektoncd/catalog/blob/main/task/kamel-run/0.1/samples/run-external-build.yaml[Camel K Tekton example]).

 As soon as you have an Integration running in your cluster, you will be challenged to move that Integration to an higher environment. Ie, you can test your Integration in a **development** environment, and, as soon as you're happy with the result, you will need to move it into a **production** environment.
 
-Camel K has an opinionated way to achieve that goal through the usage of `kamel promote` command. With this command you will be able to easily move an Integration from one namespace to another without worrying about any low level detail such as resources needed by the Integration. You only need to make sure that both the source operator and the destination operator are using the same container registry and that the destination namespace provides the required Configmaps, Secrets or Kamelets required by the Integration.

-NOTE: in order to use the same container registry, you can use the `--registry` option during installation phase or change the IntegrationPlatform to reflect that accordingly.
+When you create an Integration, the operator takes care to use an existing IntegrationKit or creating one from scratch. When you're moving your Integration across environments you'll therefore need to create an IntegrationKit accordingly. The creation of the IntegrationKit, in this case, is a simple copy of the original IntegrationKit with the `.spec.image` coming from the `.status.image` of the original IntegrationKit. Additionally, it has to be labelled as `camel.apache.org/kit.type: external`.
