fix: allow to refresh all contexts (#809)

[adietish]

depends on #809

The refresh that's available in the context menu has no effect if no context is selected.

intellij-kubernetes/src/main/kotlin/com/redhat/devtools/intellij/kubernetes/actions/RefreshAction.kt

Line 26 in 719d72c

val descriptor = selectedNode?.getDescriptor() ?: return

The refresh action should not return without doing anything. It should call ResourceModel.invalidate() instead, which then should refresh the whole tree.

intellij-kubernetes/src/main/kotlin/com/redhat/devtools/intellij/kubernetes/model/ResourceModel.kt

Lines 174 to 176 in 719d72c

	private fun invalidate() {
	logger<ResourceModel>().debug("Invalidating all contexts.")
	allContexts.refresh()

I dont know how to test this other than by debugging with breakpoints and looking at the code. Updates on the cluster are watched and acted upon. Same for the config files. I am not aware of a use case where a refresh would change the state of the resource tree :(

LGTM. refresh action seems to refresh all context if nothing selected.
