Providers for Runnable and Callable wrappers when using Kanela "executor-service-capture-on-submit" module

[alexmihailov]

While working with the Kanela "executor-service-capture-on-submit" module, I caught the ClassCastException, which I described in #1331. In this PR, I propose a solution to this problem by adding a configurable list of providers that will be able to provide the necessary wrappers over Runnable and Callable. This will help to avoid ClassCastException errors.

Sorry for letting this fall by the wayside. Taking a look now...

This is causing some issues with kamon-twitter-future

Hello! Thanks for watching my PR. I will try to fix the problems with the kamon-twitter-future module

Hi, @hughsimpson! The mistake was that in Scala 3, the PrioritizedRunnable interface in the Slick library was sealed. Therefore, I have removed the edits from the kamon-jdbc module. In my laptop, all tests for kamon-jdbc passed.

Thus, it is possible to write providers, and their implementation will be left to the user for the time being. In my case, I am using Scala 2.13 and am able to extend PrioritizedRunnable.

Nice, thanks for fixing the tests

[hughsimpson]

I did like the idea of the slick instrumentation, though. Would be good to get that in at some point

[alexmihailov]

I will try to do PR with edits for Slick and think about how I can do them for Scala 3.
