kubernetes: add multicluster support (#7266)

Browse Source 
* kubernetes: add multicluster support

Add multicluster support via Multi-Cluster Services API (MCS-API) via a
new option `multiclusterZones` in the kubernetes plugin.

When some multicluster zones are passed to the kubernetes plugin, it
will start watching the ServiceImport objects and its associated
EndpointSlices.
