Also move jdbc classes to bootstrap to reduce size and complexity of those reference checkers.
These changes reduce the total file size of these instrumentation classes by 635k, which should also result in decent memory savings.
This ensures that `dd-tracng-ot` gets included into shadow jar.
Before this patch it was included only 'by accident' via some
transitive dependencies of some instrumentations.
Should eventually revisit this to try and remove them.
Latest failure was on:
```
at ExecutorInstrumentationTest.#poolImpl '#name' reports after canceled jobs(ExecutorInstrumentationTest.groovy:202)
```
Some executors cannot handle tasks that have been wrapped into
`{Runnable,Callable}Wrapper` because they require certain subclass of
`{Callable,Runnable}` in order to work. We have a test that
effectively disables instrumentation for such executors.
This change makes sure that tasks that do not need to be
wrapped (which essentially means anything that is not lambda) still
get traced in such executors. One notable example of affected executor
type is `ScheduledThreadPoolExecutor`.
