We observed a ConcurrentModificationException. Need to use ConcurrentHashMap to fix it.

Caused by: java.util.ConcurrentModificationException: null
	at java.base/java.util.HashMap.computeIfAbsent(HashMap.java:1221)
	at org.apache.kafka.streams.kstream.internals.KStreamImplJoin$TimeTrackerSupplier.get(KStreamImplJoin.java:65)
	at org.apache.kafka.streams.kstream.internals.KStreamKStreamJoin$KStreamKStreamJoinProcessor.init(KStreamKStreamJoin.java:110)

Cherry-picked to trunk and 3.5 branch for now. -- Also pinged @showuon about 3.4 -- this we need a new RC for this hotfix to avoid introducing a very bad regression.
