Use of NoStackTraceThrowable

[kolstae]

When using kotlin coroutines the use of NoStackTraceThrowable causes problems that are really hard to find.

This code will not catch the error

    try {
        pool.preparedQuery("select true = $1").execute(Tuple.of(12)).await()
    } catch (e: Exception) {
        LOG.error("Expected: {}", e.toString())
    }

to catch the error we would need to catch Throwable which forces us to check if it's an Error.
When using futures directly, this isn't as much of a problem I guess.
