> We introduced a conditional release of Task Executor in Resource Manager in FLINK-10941.
At the moment RM directly asks TE every release timeout whether it can be released (all
depending consumers are done). We can piggyback TE/RM heartbeats for this purpose. In this
case, we do not need additional RPC call to TE gateway and could potentially release TE quicker.
