awaitSuspendExecuteBlocking
Deprecated
This API is deprecated for removal. See https://github.com/vert-x3/wiki/wiki/4.4.5-Deprecations-and-breaking-changes#deprecation-of-execute-blocking-methods-with-a-handler-of-promise. Also, this implementation is buggy. See https://github.com/vert-x3/vertx-lang-kotlin/pull/222/commits/fc3c5c5cc0c572eaddb3c2c37d07c696f75b4443#diff-162b76dc534138518a237d9a8ed527f1b3ecaca67385ea7d4357b6eff203f699R138-R217 for a fixed proposed version.
Like awaitExecuteBlocking but blockingCode is a suspend function.
