Upgrade Wildfly Swarm to Thorntail

[juangon]

Hi!

I upgraded these tests so they can pass with new Thorntail versions.

Want to highlight 2 changes made and their reasons:

• Added better ExecutionException check. As stated in https://github.com/eclipse/microprofile-fault-tolerance/blob/master/spec/src/main/asciidoc/asynchronous.asciidoc#exception-handling, ExecutionException can wrap the exceptions from Bulkhead, Timeout, etc.
• In circuitbreaker tests, I added 1 change:
  • As there could be problems when using concurrent request (it may happen that circuit isn't open when throwing the exact number of request to get expected number of requests) I changed requests to be sequential by using newSingleThread executor.

Looking good to me.

I'm sure we talked about this before, but can't remember, so I'll ask again: wouldn't enabling thorntail.microprofile.fault-tolerance.synchronous-circuit-breaker make sure that the circuit breaker will open after that exact number of requests?

Yes, I tested that and didn't work: #5 (comment)

@arjantijms I wonder if there is any plan to add microprofile 2.x samples repository, using the same approach made in microprofile-1.2-samples and microprofile-1.4-samples.

Thanks!

@juangon absolutely!

Just need some time ;)

Thanks @arjantijms ! I think you are doing a great job with these repositories BTW.
