There is tiny time window when `LockRegistryLeaderInitiator` can be stopped during `Context.yield()` invocation.
In this case the `LockRegistryLeaderInitiator` goes to the stopped state, but a new `leaderSelector` is submitted for election.
Therefore in the `LockRegistryLeaderInitiatorTests.competing()` the second initiator may not get be granted because there is uncontrolled `leaderSelector` task on background.
We can overcome it with always `this.initiator.stop()` for the `LockRegistryLeaderInitiatorTests`, but to be sure in the fix it would be better to leave as is.
Also add `@Rule Log4jLevelAdjuster` for future diagnostics

When using the internal `SequenceAwareMessageGroup` within an correlating
message handler, the messages were copied to a new collection before
checking for duplicate sequences in `canAdd()`.
This was unnecessary since we never add anything to this group, if `canAdd()`
returns true, the message is added to the store; this group is discarded.
Instead, use the message collection from the original group; although it is
not modifiable, this is not an issue because we don't need to modify it.

The race condition is present when polling task may be ran before `MessageSource<?>` has been started.
* Swap the order of `start()` in the `SourcePollingChannelAdapter`.
Since proxying is now applied only for the `MessageSource.receive()` it doesn't hurt to start it before actual proxying.
Just because it is really should be started before performing its `receive()`
* Prove the proper order with the mock test and protect ourselves for the future similar changes
* Also swap the `stop()` order in the `SourcePollingChannelAdapter.
We have to stop/cancel the polling task before discarding internal `MessageSource` lifecycle.
For example with the current state we may close an underlying resource already, but still have the last polling tick.

INT-3899 moved creating the pollingTask to start() to allow modification
of the advice chain between starts.
Since a new pollingTask is created on each start, this was fine for general advices.
However, for `AbstractMessageSourceAdvice`s, which only advise the `receive()` operation,
the advices are re-applied on every start.
When starting, first remove any advices we added on the previous start.
This handles the case when the source is a naked object, or already a proxy when supplied
to the SPCA.

The `MessagingGatewaySupport.receive()` is fully based on the `this.messagingTemplate.receiveAndConvert(replyChannel, null);`
which really just extracts `payload` from the `Message` via default `MessageConverter`.
Therefore `@Gateway` code, which expects to poll exactly `Message<?>` from the flow, is invalid at runtime with `ClassCastException`
* Expose `MessagingGatewaySupport.messagingTemplate` property as `protected` to give access for inheritors and siblings
* In the `GatewayProxyFactoryBean` use `messagingTemplate` and `replyChannel` directly from the `MethodInvocationGateway`
to invoke raw `gateway.messagingTemplate.receive(replyChannel)` bypassing any conversion and to avoid breaking changes.
* Proof the solution with `GatewayProxyFactoryBean.testReceiveMessage()`
**Consider to cherry-pick (backport) down to 3.0.x**

When `publishSubscribeChannel` is with `applySequence = true`, a `messageToSend` is overridden with `sequenceDetails` using `MessageBuilder`, therefore a new fresh `Message`.
In case of state propagation, e.g. `SecurityContextPropagationChannelInterceptor`, we just lost the state from the `ThreadStatePropagationChannelInterceptor.MessageWithThreadState` because of new `Message<?>`
* Add into `BroadcastingDispatcher` the logic to delegate `pushSequenceDetails` into `MessageWithThreadState` directly do not lose the `state`
* Make `ThreadStatePropagationChannelInterceptor` as `MessageBuilderFactory`-aware and use it to rebuild an `original` `Message<?>` in the `MessageWithThreadState` to populate `SequenceDetails`

Fix mutation in the `ThreadStatePropagationChannelInterceptor`
Since `BroadcastingDispatcher` invokes `pushSequenceDetails` for each subscribed handler,
make `MessageWithThreadState` as immutable and return a new instance via `cloneWithSequenceDetails()` method with particular `sequenceDetails`.
Previous mutable solution ended up with the issue of concurrent modification.
* Introduce `CloneableMessage` abstraction to let any custom `Message` to return `MessageBuilder` with desired context.
* Introduce `DelegatingMessageBuilder` as an extension of the `MessageBuilder` to let custom `CloneableMessage` to return desired customization.
* Add into `MessageBuilder#fromMessage()` `if` for the `CloneableMessage`
* Add into `MutableMessageBuilder` a `warn` about `CloneableMessage`
* Revert changes in the `BroadcastingDispatcher` in favor of `CloneableMessage` in the `MessageBuilder`

In some places we start `Cache` but doesn't close/destroy it in the end.
That sometimes causes conflicts with the already started GemFire from other tests or wrong state around `BeanFactoryLocator`
* Ensure `Cache` destroy in the end of each test
* In addition destroy `Region` as well to avoid unexpected race conditions, too
* Plus optimize some tests to start `Cache` and `Region` only once per test class, not for each test method
From here I can say that it even would be better to start `Cache`, and therefore whole GemFire, only once per entire Gemfire module test suite.
But that is fully different story.
