fix: apps that use an rclone config may not be down-able

[starpit]

Describe the bug
If the rclone config file in question used for up is not available on the machine doing down, then the down will fail. This is because down depends on templating the application into the llir, in order to know which resources to delete. And the templating step looks for the rclone config file...

one fix would be to have down instead just kill all runname-labeled resources. we could leverage the GetAllResourcesFromSelector from odo. https://github.com/redhat-developer/odo/blob/main/pkg/kclient/all.go

alternatively, we could somehow render rclone config file loading into warnings when doing down...
