refactor(core): Convert Cluster filters to react

[caseyhebebrand]

Create ClusterFilter react component. Remove unused angular code, and ensure backward compatibility.

Note: FilterCheckbox component already existed in two places. This PR just pulls it out into its own file so the load balancers, clusters, and functions can use it in their filter sections.

👏 Really good work! The new ClusterFilters component is really easy to follow.

[christopherthielen]

Should this be checking if the new state is actually the Clusters State?

[caseyhebebrand]

That is a good point. The previous version does not do that, but adding that check makes sense from an efficiency standpoint.

May want to memoize this for when serverGroupData is large.

Suggested change

	const labelsMap = buildLabelsMap(serverGroupData);
	const labelsMap = useMemo(() => buildLabelsMap(serverGroupData), [serverGroupData]);
