The multiplexed session maintainer used a ScheduledExecutorService with a core pool size of zero. This can cause high CPU usage on Java 8 due to https://bugs.openjdk.org/browse/JDK-8129861. Also on higher versions of Java, it is better to use an executor with at least one core thread, instead of letting the executor create a new thread every time a task needs to be executed. Fixes #3313 Fixes GoogleCloudPlatform/pgadapter#2249 Fixes googleapis/java-spanner-jdbc#1736
