Nodes currently will try and resolve network parameters from the network map and fail if it not available, rather than preferring the availability of a node they are currently interacting with.
A migrated notary identity could not be resolved on new nodes added post-migration, but the old identity is available in the network parameter notary whitelist.
Added a test that covers both bugs in a single reproduction test that simulates the scenario in which both were uncovered.
First cut of telemetry integration.
Open telemetry can be enabled in two ways, first is via an opentelemetry java agent specified on the command line. With this way you get the advantage of spans created from other libraries, like hibernate. The java agent does byte code rewriting to insert spans.
The second way is with the open telemetry driver (that links with the opentelemetry sdk). This is a fat jar provided with this project and needs to go into the node drivers directory.
As a side effect of enabling warnings for Artemis was the following messages to be produced in the Node's log:
```
[WARN ] 2022-05-16T14:53:01,203Z [main] core.server. - AMQ222165: No Dead Letter Address configured for queue rpc.server in AddressSettings
[WARN ] 2022-05-16T14:53:01,203Z [main] core.server. - AMQ222166: No Expiry Address configured for queue rpc.server in AddressSettings

```
To suppress them a dedicated filter been added.
The change to logging configuration been tested locally using out-of-process integration tests.
Fixes DDoS attack mentioned on the Jira ticket.
PR upgrades Artemis library to version 2.19.1.
This is our own release of Apache Artemis library which has vulnerability fix for v2.20 applied.
**_Breaking changes discovered during Artemis upgrade:_**
1. When the queue is created as temporary, it needs to explicitly be specified as non-durable.
2. By default, Artemis Client performs Host DNS name check against the certificate presented by the server. Our TLS certificates fail this check and this verification has to be explicitly disabled, see use of: `TransportConstants.VERIFY_HOST_PROP_NAME`.
3. Artemis Server now caches login attempts, even unsuccessful ones. When we add RPC users dynamically via DB insert this may have an unexpected outcome if the user with the same `userName` and `password` was not available previously.
To workaround permissions changing dynamically, authorization and authentication caches had to be disabled.
4. When computing `maxMessageSize`, the size of the headers content is now taken into account as well.
5. Artemis handling of start-up errors has changed. E.g. when the port is already bound.
6. A number of deprecated APIs like: `createTemporaryQueue`, `failoverOnInitialAttempt`, `NullOutputStream`, `CoreQueueConfiguration`.
7. Log warning message is produced like: `AMQ212080: Using legacy SSL store provider value: JKS. Please use either 'keyStoreType' or 'trustStoreType' instead as appropriate.`
8. As reported by QA, Artemis now produces more audit logging more details [here](https://r3-cev.atlassian.net/browse/ENT-6540). Log configuration been adjusted to reduce such output.
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.
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.
