As reported in [CORDA-1609](https://r3-cev.atlassian.net/browse/CORDA-1609),
`CordaRPCClientConfiguration.default` is not accessible from Java since
`default` is a reserved keyword.
As part of the refactor made in #2831, `CordaRPCClientConfiguration` went
from being a data class to an interface with a backing implementation of
type `CordaRPCClientConfigurationImpl`.
This resulted in Java users having to rewrite code that was on the form:
```java
final CordaRPCClient client = new CordaRPCClient(
nodeAddress, CordaRPCClientConfiguration.DEFAULT
);
```
to something like this:
```java
final CordaRPCClient client = new CordaRPCClient(
nodeAddress, CordaRPCClientConfiguration.Companion.default()
);
```
However, this does not work. The user would get a compilation error because
`default` is a reserved keyword in Java.
Since `CordaRPCClientConfiguration` has been made an interface, there is no
easy way of introducing a static final field on the interface from Kotlin.
Consequently, I've changed this back to using a `class` with a static field
named `DEFAULT` instead of the static method `default()`.
It should be noted that `default()` / `DEFAULT` is currently only used
internally to pass in default values in `CordaRPCClient.kt` and
`CordaRPCClientUtils.kt`. That said, it is exposed as part of our API
surface and consequently shouldn't be broken.
The latter means that in the above example, the user would actually not
have to provide the parameter at all:
```java
final CordaRPCClient client = new CordaRPCClient(nodeAddress);
```
As can be seen from the definition of `CordaRPCClient`:
```kotlin
class CordaRPCClient private constructor(...) {
@JvmOverloads
constructor(
hostAndPort: NetworkHostAndPort,
configuration: CordaRPCClientConfiguration = CordaRPCClientConfiguration.DEFAULT
) : this(hostAndPort, configuration, null)
```
The mentioned [refactor](7a077e76f0 (diff-0948c125db93a22263eb81eaf3161c17R65))
did not make it into the 3.1 release, so from an API-stability perspective,
this change can be applied without affecting our commitment to a
backwards compatible API..

* Finality Flow sets the current step to NOTARISING only if the actual notarization is performed.
node-api now depends on this module and upcoming changes will use this as well rather than having to depend on node-api.
EnumEvolveTests.deserializeWithRename and EnumEvolveTests.multiOperations are temporarily ignored since their test resources can't be regenerated due to bugs.

Current logic in `CashWidget` is not handling well updates done in close succession, i.e. less than 1 second.
And such frequent updates do indeed happen, e.g. from: `net.corda.client.jfx.model.ContractStateModel#cashStates`
where `list` is modified twice.
Also use `.toDecimal()` instead of `.quantity`to have amount represented in pounds rather than in pennies.
(cherry picked from commit 952cc35)
- Existing embedded Shell connects via RPC including checking RPC user credentials (before was a direct use of CordaRPCOps): in dev mode when console terminal is enabled, node created `shell` user.
- New Standalone Shell app with the same functionalities as Shell: connects to a node via RPC Client, can use SSL and run SSH server.

With network parameters the CN is no longer needed to identify notaries. This frees it up to be used in the node's name alongside the other attributes.
Also, the identity generation logic has been simplified, removing the need to have magic string values for storing distributed identities in the keystore. Now there are just two alias prefixes: "identity" as it was previously, and "distributed-notary".
Copying of the node-info files moved out of Cordform and into NetworkParametersGenerator (which is now called NetworkBootstrapper). This class becomes an external tool to enable deployment of nodes in a test setup on a single filesystem.
* * Document TestIdentity entropy and enforce that it actually works
* Ledger/transaction DSL default notary with fresh key
* MockServices default identity with fresh key
* makeTestIdentityService now takes vararg

* Add handling of network parameters mismatch
Change NetworkMapClient and updater, add handle in
AbstractNode that results in node shutdown on parameters mismatch. Later
on we should implement proper handling of parameters updates.
Add tests of NetworkParameters wiring.
When node starts with compatibilityZone url configured it takes
networkParameters from the networkMap.
* Permit only one network parameters file
On node startup network parameters are read from node's base directory,
we permit only zero or one files to be there. If network map server is
configured the parameters can be downloaded at startup (if not present
in the directory already).
* Update docs on network map endpoints
* Redo legal name validation rules so that direction change chars are rejected
* Split name validation into minimal rules that all nodes can require, plus extended rules that the Doorman will apply (and we may need to change, without updating the entire network).
* Break down name validation rule sets to better match expectations

* Applied changes in cordformation following review feedback from CA.
The motivation for this came with the recent change that a default notary is started by the driver, which if ignored will leak the notary process.
Also, waitForAllNodesToFinish() has been replaced by a driver parameter.
network-parameters file read in by the node at startup, of which only the list of notaries is used. For now, the driver and MockNetwork have been updated to require notaries to be started first. This is so that the same set of network parameters can be defined for all the nodes.
CN in the legal name is not longer disallowed since it's no longer reserved for distributed notary names.
Single-node notaries now only have one identity, their main identity. Nodes part of a cluster continue to have two.
(Based off Kasia's work)
* [CORDA-442] let Driver run without network map
- Nodes started by driver run without a networkMapNode.
- Driver does not take a networkMapStartStrategy anymore
- a new parameter in the configuration "noNetworkMapServiceMode" allows for a node not to be a networkMapNode nor to connect to one.
- Driver now waits for each node to write its own NodeInfo file to disk and then copies it into each other node.
- When driver starts a node N, it waits for every node to be have N nodes in their network map.
Note: the code to copy around the NodeInfo files was already in DemoBench, the NodeInfoFilesCopier class was just moved from DemoBench into core (I'm very open to core not being the best place, please advise)
The current use of SSL RPC relies on access to the node's keystore file, and further to that some uses where using the NODE_USER to login on the p2p port.

* Change how NetworkHostAndPort is parsed
Change from using a global extension function to parse
NetworkHostAndPort strings, into using a function on the companion
object. This is a lot easier for Java interop and matches the common
style used elsewhere both in Corda and in Java libraries.
* Move JAR extraction into new utils file
* Move path verification function to ArtemisUtils
Move path verification function "requireOnDefaultFileSystem()" to new
ArtemisUtils.kt file, as this makes more sense from a Java interop
perspective.

* Add JvmName to ConcurrencyUtils
* Move Iterable<ServiceInfo>.containsType() into Simulation, as it's only useful when verifying
setup of a simulated case. Resolves ServiceInfoKt class being generated.
* Move FlowHandle.notUsed() into the one place it's actually called, so Kotlin stops creating a FlowHandleKt class.
