Support multiple DSL

[Delawen]

As a user I want to be able to select the type of workflow I am generating (Camel route, Kamelet, Kamelet Binding,...).

Implementation details

The API can provide multiple DSL formats on the /integrations/customResources endpoint. There should be some way the user can select which one of all those source codes they want to use.

Swagger is a bit lazy, but the response is a Map that returns all possible source codes with a key that represents what the source code is for (on our current case, "Kamelet" or "KameletBinding").

[Delawen]

We can either have an explicit drop down selection or we can refresh the catalog based on the steps selected. So when you select one step that restricts, it will only show compatible steps.

You start with a camel connector... it can still be kamelet binding or kamelet or camel route.
Then you select an if -> boom, kamelet binding discarded.
Or if you select a kamelet sink -> ahh, no camel route then.
