* ENT-2636: Introduce ModeSelectingChannel
Next step: Add an integration test.
* ENT-2636: Explicitly retain/release ByteBuf
* ENT-2636: Use ByteBuf API and stop using `java.nio.ByteBuffer`
* ENT-2636: Add new optional FirewallConfiguration parameter
* ENT-2636: Simplify implementation of ModeSelectingChannel
* ENT-2610: Create integration test to check response on TCP call and fixes to ModeSelectingChannel
* ENT-2610: Extend integration test fixes to ModeSelectingChannel
Doesn't currently work well for longer messages.
* ENT-2610: Extend integration test fixes to ModeSelectingChannel
Doesn't currently work well for longer messages.
* ENT-2610: Fixes to ModeSelectingChannel so it works well for longer messages.
* ENT-2610: Reflect `healthCheckPhrase` from `FirewallConfiguration` onto `AMQPConfiguration`
* ENT-2610: Incorporate review comments by @mnesbit
* ENT-2636: Extend the test to drip feed bytes one-by-one.
Also remove TRACE level packet logging for speed and log space reduction.
Logging-wise the following printed into the log every time TCP echo performed:

* ENT-2610: Documentation update to include optional `keyStorePrivateKeyPassword`.
* ENT-2610: Documentation update to include optional `keyStorePrivateKeyPassword`.
* ENT-2610: Disruptive change to `CertificateStore` (will cause compilation failures)
* ENT-2610: Address compilation failures caused by separation of `storePassword` and `keyPassword` e.g. in `X509KeyStore`
* ENT-2610: Docs update to flag that passwords have to be the same due to Artemis limitations.
* ENT-2610: Make changes to `bridge` module.
Make private key password optional in `BridgeSSLConfigurationImpl` and extend `ConfigTest`.
Also improve exception reporting when necessary option is missing.
* ENT-2610: Fixes to `bridge` integration tests.
* ENT-2610: Whenever it comes to Dev node certificates ensure that private key password is the same as store password
or else Artemis is not going to accept that, see comment in DevIdentityGenerator.
* ENT-2610: More unit test fixes
* ENT-2610: More integration tests fixes
* ENT-2610: Fix netty code to use `privateKeyPassword` where necessary
* ENT-2610: Remove the use of `keyPassword` for `trustStore`
* ENT-2610: Compilation fixes after merge from `master`
* ENT-2610: Add an integration test which proves that diff. passwords work
* ENT-2500: Refactoring to allow FirewallAuditService have inbound as well as outbound logging.
Change some visibility modifiers to `private`. Use in-place initialisation where possible.
* ENT-2500: Record accepted package coming into Float
* ENT-2500: Introduce optional BridgeAuditService in `nodeApi` module
* ENT-2500: Switch FirewallAuditService to use `ApplicationMessage` and bind outgoing message stats.
* ENT-2500: Introduce scheduled executor and audit service configuration.
* ENT-2500: Stats formatting.
* ENT-2500: Stats formatting unit test.
* ENT-2500: Minor changes to LoggingFirewallAuditService and its unit test.
* ENT-2500: Additional configuration parameter documentation update.
* ENT-2500: Supply optional parameter.
* ENT-2500: Address PR comments.
* ENT-2500: Make API more consistent by using `RoutingDirection`, re-jig `State` data structure, improve unit test.
* ENT-2500: Add breakdown by endpoint address.
* ENT-2500: Compilation fix after rebase in `master`.
* ENT-2500: Making `AuditServiceConfiguration` not optional and supplying default settings.
Also few minor changes.
* zookeeper doc
* explicitly mention hot/hot is not supported
* change zookeeper to ZooKeeper
* change doc link to v3.5.3
* add note stating only zookeeper v3.5.3-beta is compatible
