c1b7b1cb75 Add information on who started flow on a node. (#549)
* Add information on who started flow on a node with name where possible.
Add sealed class holding information on different ways of starting a flow: RPC, peer, shell, scheduled.

* Remove invokeFlowAsync from ServiceHub, move it to ServiceHubInternal.
We shouldn't be able to start new state machines from inside flows.

d2d7cbc9ec CORDA-299: Remove progress Observable from FlowHandle, unless explicitly requested. (#513)
* Remove progress Observable from FlowHandle, unless explicitly requested.
* Refactor FlowHandle creation into FlowStateMachine.
* Prevent server-side queue subscription for dummy Observable.
* Refactor so that RPC client does not receive any unused progress Observables. This is the simplest way of ensuring we have no dangling "hot" Observables when the RPC client closes.
* Test flow has correct handle.
* Resolve some compiler warnings.
* Document how starting a flow does not involve progress tracking by default.
* Update changelog and release notes for RPC API.
* Rename new RPC API to startTrackedFlow().
* Remove optimisation because of its affect on the client-side.
* Update documentation.

d35bd74596 Standardise identities used in tests, demos, etc.
Standaridise the identity names of Alice, Bob and Charlie, notary, map service, etc. in order
to ensure consistency across the code base and reduce number of places that have to be changed
to introduce proper X.500 names.

Move Alice, Bob & Charlie identities into the utilities package so they can be used in demos

36d5d0d7b2 Refactor of CompositeKeys to implement PublicKey interface. (#433)
* Make CompositeKey implement PublicKey

The initial implementation of composite keys as their own distinct class separate from PublicKey
means that the keys cannot be used on standard classes such as Certificate. This work is a beginning
to modifying CompositeKey to being a PublicKey implementation, although significant further work
is required to integrate this properly with the standard Java APIs, especially around verifying
signatures using the new key type.

* First stage of making CompositeKey implement PublicKey interface. Revert to using PublicKey everywhere we expect a key.

* Move algorithm and format into companion object (#432)

Move algorithm and format into companion object so that they can be referenced from other
classes (i.e. the upcoming signature class).

* Add simple invariants to construction of CompositeKey.
Builder emits CompositeKeys in simplified normalised form. Forbid keys with single child node, force ordering on children and forbid duplicates on the same level. It's not full semantical normalisation.

* Make constructor of CompositeKey private, move NodeWeight inside the class.
Add utility function for Kryo deserialization to read list with length constraints.

262c87a5c6 Integrate CRaSH shell (SSHD). Joint effort between Mike Hearn and Marek Skocovsky.
The shell is embedded in the node and offers the ability to monitor
and control the node via the launching terminal.

Still to do:

* Switch to a fork of CRaSH that we can maintain ourselves, and merge in Marek's SSH patch so we can enable SSH access.
* Add persistent command history that survives restarts.
* Tab completion for the 'flow' and 'run' commands.
* Remove the 'jul' command and replace it with a command that lets you see and tail the log4j logs instead.
* Fix or remove the other crash commands that have bitrotted since 2015.
