Summary: Renames contenderID into componentId
Key: FLINK-32556
URL: https://issues.apache.org/jira/browse/FLINK-32556
Project: Flink
Issue Type: Sub-task
Reporter: Matthias Pohl
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.
