slow shutdown in testing

[danmoorenhs]

hi there,

we're experiencing very long spring boot shutdown times which makes our automated testing slow and painful - around 20 seconds per listener/session - is there a way we can configure or control/override this behaviour?

these lines from our logs seems to be related..

`{"@timestamp":"2022-08-09T11:57:05.802Z","level":"INFO","service":"ehr-transfer-service","class":"SQSMessageConsumer","line":"229","message":"Shutting down ConsumerPrefetch executor","environment":"local"}

{"@timestamp":"2022-08-09T11:57:06.305Z","level":"INFO","service":"ehr-transfer-service","class":"SQSSession","line":"421","message":"Shutting down SessionCallBackScheduler executor","environment":"local"}`

thanks!

I believe this is caused by the hardcoded 20 seconds WAIT_TIME_SECONDS in ConsumerPrefetch.

amazon-sqs-java-messaging-lib/src/main/java/com/amazon/sqs/javamessaging/SQSMessageConsumerPrefetch.java

Line 65 in c16c185

protected static final int WAIT_TIME_SECONDS = 20;

This should be user configurable for cases like testing.
