Do not keep a flow in for observation if it receives an unexpected
session end message while in `ReceiveFinalityFlow` and
`ReceiveTransactionFlow` (due to being called by the former).
This is done by checking the message of the `UnexpectedFlowEndException`
that is thrown when a session end message instead of a data message and
if the stacktrace has `ReceiveTransactionFlow` at the top, after
removing statemachine stack frames.
Checking the stacktrace for `ReceiveTransactionFlow` is important
because the unexpected session end session message is only ok if a
transaction has not already been received. For example, if
`ResolveTransactionsFlow` is in the stack, then this indicates failure
when receiving transaction dependencies on a transaction that should be
recorded.
Also added a test that highlights that the `UnexpectedFlowEndException`
caused by the session end message can be caught, therefore users can
determine their own behaviour if desired.
Remove the shell code from the OS code base, this includes the modules:
- `:tools:shell`
- `:tools:shell-cli`
The shell will be run within a node if it exists within the node's `drivers` directory.
This is done by using a `URLClassloader` to load the `InteractiveShell` class into Corda's JVM process and running `startShell` and `runLocalShell`.
Running the shell within the `:samples` will require adding:
```
cordaDriver "net.corda:corda-shell:<corda_shell_version>"
```
To the module's `build.gradle` containing `deployNodes`. The script will then include the shell in the created nodes.

Checkpoint dumping of paused flows was not working because the dumper
expects a flow to have a `FlowState` of `Unstarted` or `Started`,
however due to a memory optimisation paused flows have their `FlowState`
set to `Paused`. This was causing causing an exception as well as a loss
of potentially useful information.
A flag `alwaysDeserializeCheckpoint` has been added to
`Checkpoint.Serialized.deserialize` which skips the memory optimisation
and forces the deserialization of the flow's `FlowState`.
Paused flows are now included in the dumped output along with their real
`FlowState` which is useful to users even if the flow is paused rather
than waiting for something to complete.
The status of the flow has also been added to the JSON output to assist
users in debugging their flows.
A public version of `FlowManagerRPCOps` which does not live in an
internal package has been added. This new interface shares the same name
as the internal one.
Because of the name sharing, the internal version has been
`@Deprecated`.
`FlowManagerRPCOpsImpl` implements both the new and old interfaces. This
allows for backwards compatibility, allowing old shells or clients to
call the old interface on newer nodes without breaking.
This is a newly built internal version of the library which in particular upgrades `org.apache.mina:mina-core` to version `2.0.22` eliminating NexusIQ vulnerability.
