Node with multiple group tags

[JasonTam]

Hi
I came across a scenario where I'd like to have non-mutually exclusive groups.
ex) For every kubeflow task, I want to establish some context for that task using the same node
Group1: {A, B, C}
Group2: {A, D, E}

However, there's an explicit exception for this scenario:

kedro-vertexai/kedro_vertexai/grouping.py

Lines 92 to 96 in 445136f

	if len(grouping_tags) > 1:
	raise GroupingException(
	"Inconsistent tagging for grouping, multiple tags"
	f"with grouping prefix found in node {name}"
	)

Would things necessarily break if we allow this to happen? Or is this more of a warning to the user? If so, should we change it to be a non-blocking warning?

@JasonTam The current implementation assumes mutually exclusive groups - each node can only belong to one group. In your example when execution would run a pipeline with grouping: Group1 -> Group2 it would require node A to be executed twice which isn't correct.
