Describe the bug

When shutting down the application, runnable submitted through ManagedExecutor are interrupted before the configured timeout.

This is because the shutdown task runnable created in io.quarkus.runtime.ExecutorRecorder has a bug in computation of time remaining before interruption.

long start = System.nanoTime();
int loop = 1;
for (;;) {
    // This log can be very useful when debugging problems
    log.debugf("loop: %s, remaining: %s, intervalRemaining: %s, interruptRemaining: %s", loop++, remaining,
            intervalRemaining, interruptRemaining);
    try {
        if (!executor.awaitTermination(Math.min(remaining, intervalRemaining), TimeUnit.NANOSECONDS)) {
            long elapsed = System.nanoTime() - start;
            intervalRemaining -= elapsed;
            remaining -= elapsed;
            interruptRemaining -= elapsed;

Time elapsed since loop start is cumulated and subtracted from *remaining variables at each iteration, but should be removed from the initial values.

Expected behavior

Submitted runnable should be terminated after 60s

Actual behavior

Submitted runnable is interrupted after about 11s

How to Reproduce?

Build and run the attached sample project with

1. ./mvnw clean package
2. java -Dquarkus.thread-pool.shutdown-check-interval=1s -Dquarkus.thread-pool.shutdown-interrupt=60s '-Dquarkus.log.category."io.quarkus.thread-pool".level=DEBUG' -jar target/quarkus-app/quarkus-run.jar
