Provide C8 built-in connectors with the desktop modeler

[MaxTru]

What should we do?

Retrieve and show C8 SaaS present Connectors (technically via element templates) and offer for modeling.

Probably in order to do this, we need to:

• [ ] Have some context in DesktopModeler (e.g., via project context)
• [ ] In context store Camunda Cloud connection for a given diagram
• [ ] Set target cluster C8 SaaS or self-managed cluster for diagram context
• [ ] If target cluster is C8 SaaS 8.x, then retrieve templates (conntectors) and show them

Precondition:

• [ ] https://github.com/camunda/camunda-modeler/issues/2820

Dependency:

• [ ] Web Modeler to offer API for us to retrieve available connector element templates for given cluster (@CatalinaMoisuc )

Why should we do it?

To offer C8 SaaS Connectors in Desktop Modeler

Is there a plan when the connector will be avail in desktop modeler? I also found the connector that published to the on-prem camunda engine ( stood up using docker compose) does not run. It just stay there. When the desktop modeler starts to support the connector, I assume the on-prem engine will just work?

Thanks

@emailtowalter Connectors will only work out of the box when using Camunda SaaS.

At some point though you'll be able to spin up the connector run-times on C8 self-managed yourself (to accomplish the same thing).
