> We introduced {{contenderID}} in a lot of places with FLINK-26522. The
> original multi-component leader election classes of FLINK-24038 used
> {{componentId}}.
> Revisiting that naming made me realize that it's actually wrong. A contender
> is a specific instance of a component that participates in the leader
> election. A component, in this sense, is the more abstract concept.
> {{contenderID}} refers to an ID for the specific contender instance but the
> IDs we're sharing are actually referring to a Flink component and therefore,
> are the same between different contenders which compete for leadership for
> the same component. This contradicts the definition of an identifier.
