Provide UI to configure access to API Doc (Swagger) in REST Configuration

ui experience:
> user has little guidance on UI
> no documentation available on how to expose Swagger info
> misleading/not-functional options in UI (i.e. enableCORS checkbox)
> textbox "port" (in Mac) user input goes backwards (yes, backwards!) handled with https://issues.jboss.org/browse/FUSETOOLS-3254
> textbox "contextPath" (in Mac) user input goes backwards (yes, backwards!) handled with https://issues.jboss.org/browse/FUSETOOLS-3254

result:
> not possible from UI to expose Swagger info

expected:
> options available on UI to expose API definitions

workaround:
> manually add all necessary parameters:

• add: contextPath="camel"
• add: port="8080"
• add: apiContextPath="api-docs"
• add: <apiProperty key="cors" value="true"/>
