* CORDA-3668: Prevent AttachmentURLConnection from assigning ALL_PERMISSIONS to classes inside an attachment.
* Strengthen the comment warning about AttachmentURLConnection.getPermission.
* CORDA-3596 Record flow metadata
Record flow metadata during the zero'th checkpoint that occurs before
calling the flow's `call` function.
This required adding an RPC call's arguments to the `InvocationContext`
that gets created. These arguments are then accessible within the
statemachine and from the `Checkpoint` class. The arguments are then
extracted when recording a flow's metadata inside of
`DBCheckpointStorage`.
Updated the size of the started by column to 128 since it was not long
enough to hold the fully qualified class of a service that started a
flow.
* CORDA-3596 Remove arguments from in-memory checkpoint
When executing a flows first real suspend (from flow code) the arguments
contained in the `InvocationContext` are removed. This saves holding
these arguments for the whole lifecyle of a flow.
* CORDA-3596 Increase `cordapp_name` column to 128
* CORDA-3596 Join metadata by `flow_id`
Due to changes in where metadata is recorded, there is no need for
having `invocation_id` as the metadata table's primary key. The
`flow_id` is now the primary key of the table and is used to join to the
main checkpoints table.
The `invocation_id` has been removed from the checkpoints table since it
is not needed for the join anymore.
* CORDA-3596 Remove `received_time` from metadata table
* CORDA-3596 Remove unused `StartReason` enum
* CORDA-3596 Simple `DBCheckpointStorageTests` for metadata

Deprecate FlowAsyncOperation and reimplement public versions FlowExternalOperation and FlowExternalAsyncOperation.
await added to FlowLogic to allow easy calling from both Java and Kotlin. There are two overrides of await (one for FlowExternalOperation and FlowExternalAsyncOperation).
Implementations of FlowExternalOperation return a result (written as blocking code) from their execute function. This operation will then be executed using a thread provided by the externalOperationExecutor.
Implementations of FlowExternalAsyncOperation return a future from their execute function. This operation must be executed on a newly spawned thread or one provided by a thread pool. It is up to developers to handle threading in this scenario.
The default thread pool (externalOperationExecutor) can be configured through the flowExternalOperationThreadPoolSize node config.
The current implementation leaves FlowAsyncOperation alone, meaning that any developers that have used it (even though it is internal) won't need to change their apps. If this was not concern I would delete it completely and replumb the state machine code. Instead, it has been marked with @DoNotImplement and executeAsync is annotated with @Deprecated
