Update Corda 5 to compile and run with the Kotlin OSGi bundles
Migrate the Corda 5 repository so that:
All artifacts are compiled against Kotlin OSGi bundles, including test artifacts.
All tests are run using Kotlin OSGi bundles.
When publishing Corda 5 artifacts, their POMs should also depend on Kotlin OSGi bundles rather than the basic Kotlin jars.
This change will also upgrade Corda 5 to use Kotlin 1.4.10, since we have OSGi bundles for this version.
