1. feat(corda): add Corda ledger support …

   Primary Changes
   ===============
   
   1. Corda all-in-one image
   
   Note: In this state of it it runs the full
   sample with all the nodes and web servers
   which ends up using 11GB of RAM so we will
   have to thin this down eventually once the
   Corda connector is otherwise passing the tests
   with this container. Once we are at that
   point we can start removing parts of the
   AIO container to reduce RAM usage and verify
   that the tests are still passing without
   issues or not.
   
   2. Corda ledger connector server as a JVM app
   (uses the "kotlin-spring" generator template from OpenAPI)
   The only file that is non-generated in that folder is the
   service implementation called ApiPluginLedgerConnectorCordaServiceImpl.kt
   
   TODO: make sure the generated folder can be cleaned and regenerated
   without having to manually re-add the implementation file mentioned
   above.
   
   3. The Typescript interfaces necessary for the NodeJS API server to
   be able to communicate with the JVM app in a transparent manner where
   higher level plugins can talk to Corda through the connector in Typescript
   without realizing that they are actually sending HTTP requests over the
   network to the JVM app.
   
   4. Home-grown, JSON-embedded DSL is used to define the flow params.
   
   5. Lots of to-dos still, but there are end to end tests passing
   and everything is working with containers.
   
   6. Jar deployment is only partially supported for now: if the jar
   is already present on the node, then calling the jar deploy endpoint
   on the connector will make sure to add that jar to the classpath of
   the connector as well. If however the jar is not deployed on the corda
   node itself then it will no work just yet because the SSH connection
   is not yet implemented in the corda connector.
