If you hold the lock, you are the leader. This simple idea gets you
a long way if there is no "native" leader initiator. E.g. you
can use this with a RDBMS with JdbcLockRegistry.
Add some docs on leader election under "endpoints"
Make thread name for leader initiator unique
In case there are multiple instances in the same context we would
like to be able to spot them in the logs.
INT-4058: Polishing
* Code refactoring in the `LockRegistryLeaderInitiator`: SI use 120 line length
* Add `Assert.notNull()` for required properties
* Add `this.lock.unlock()` and `Thread.sleep(LockRegistryLeaderInitiator.this.busyWaitMillis)` into the `catch` block to let distributed elections to work.
Otherwise there is a big chance that we will acquire the lock and become a leader again just after `yield()`
* Change `LockContext.toString()` to use simple `String` concatenation which is optimized by compiler to the `StringBuilder`.
That let to have some better micro-performance compared with with extra `Formatter` object in case of `String.format()`
* Add `JdbcLockRegistryLeaderInitiatorTests`
* Fix `yield()` logic based on the `Future.cancel(true)`.
Since one `FutureTask.cancel(true)` makes it as `INTERRUPTED` any subsequent `yield()` does not make any effect, therefore our infinite selector loop isn't interrupted one more time.
* Reschedule the `LeaderSelector` in the `yield()` after cancel(true).
* Rework `catch` in the selector loop just to the `InterruptedException` and `return null;` to stop looping and let reschedule the selector.
* Add one more `onRevoked` logic into the `final` of the selector loop to notify that we have lost leadership during `stop()`
* Improve `JdbcLockRegistryLeaderInitiatorTests` to ensure that several `yield()` on the same initiator work well.
* Add `What's New` note.

The `PropertySourcesPlaceholderConfigurer implements BeanFactoryPostProcessor, PriorityOrdered`
meaning that it is run before any other regular `BeanFactoryPostProcessor`,
like the `IntegrationConfigurationBeanFactoryPostProcessor` has been before.
With such an order any `BeanDefinition` declaration from the `IntegrationConfigurationBeanFactoryPostProcessor` process
ended up without `PP` resolutions.
* Rework `IntegrationConfigurationBeanFactoryPostProcessor` to the `BeanDefinitionRegistryPostProcessor`,
which makes it be loaded as early as possible. See `PostProcessorRegistrationDelegate`:
````java
// Now, invoke the postProcessBeanFactory callback of all processors handled so far.
invokeBeanFactoryPostProcessors(registryPostProcessors, beanFactory);
invokeBeanFactoryPostProcessors(regularPostProcessors, beanFactory);
````
* Modify `EnableIntegrationTests` and `ChannelSecurityInterceptorSecuredChannelAnnotationTests` to ensure that the change
meets the `PP` and `SpEL` resolutions during bean definition phase.

Since the `RequireThisCheck` doesn't see parents for anonymous classes (e.g. `Runnable` callback), its report doesn't contains the outer class name with `this.`,
therefore we still have to fix those cases manually.
Thanks to the wrong `replacer` just with `this.` we have uncompilable code enough easy to find problems.
Not so easy to fix for good readability though...

The `RedundantModifierChecker` doesn't catch all errors at once.
We need run `check -> fixModifiers` pair several times to reach `SUCCESSFUL`.
The `fixThis` has been ported from the SA, but without applying.
* Polishing for `fixModifiers.gradle`
* Fix all redundant modifier with the `fixModifiers.gradle`
NOTE: Since all these task modify files on Windows we have to run them with the `-Dfile.encoding=UTF-8`.
Otherwise they are read and write with the Windows default `cp1251` making them incompatible with Unix system.

Some other polishing
`tryAcquire` outside of the `lock`
Move `tryAcquire` within the `addMessageToGroup` outside of `lock`.
But do that only for groups which already exist.
For the new groups we have a fresh `UpperBound`, so no need to worry about dead lock and
we can obtain a permit immediately.

* `ConnectionToConnectionTests`: increase timeout and count iteration. Previously with `1sec` we may lose some events. And we can't just rely on the `10sec`,
because the last iteration will be so long
* `TcpOutboundGatewayTests`: `500ms` is so big timeout to wait for the `Exception` that in the high load environment we can yield to other Thread so long.
Like in our case to `server` Thread to send the reply for us. Therefore decrease the Exception timeout to the `50ms` and increase server delay to `2sec`
* `StompInboundChannelAdapterWebSocketIntegrationTests`: remove `@Qualifier("taskScheduler")` as a potential candidate to test against latest SF changes.
We're fine with `SF-4.2.2` and it is just a test-case. So, I don't see reason to wait for their fix here.

The `IntegrationMBeanExporter` doesn't register any `@ManagedResource` automatically.
Its `autoDetection` is disabled by default.
Hence such a components like `AbstractMessageGroupStore`
or `WireTap` aren't exposed to the JMX by the `IntegrationMBeanExporter`.
From other side `MBeanExporterHelper` aims to help to avoid duplicate exposing if
an `MBeanExporter` is presented in the CTX.
But `MBeanExporterHelper` did that unconditionally just for the whole `org.springframework.integration` package.
Therefore components which aren't EIP ones aren't exposed to the JMX at all.
* Fix `MBeanExporterHelper` to deal for exclusion based on the `@IntegrationManagedResource` annotation.
* Remove `@IntegrationManagedResource` from those components which aren't EIP.

Previously there were a lot of noise from the `PostProcessorRegistrationDelegate$BeanPostProcessorChecker` for early access for beans.
That may produce some side-effects when some of `BeanFactoryPostProcessor`s won't adjust those beans.
The issue is based on two facts:
1. Loading beans from `BPP`, e.g. `IntegrationEvaluationContextAwareBeanPostProcessor` (or `ChannelSecurityInterceptorBeanPostProcessor` - https://jira.spring.io/browse/INT-3663)
2. Loading beans from `setBeanFactory()/setApplicationContext()` container methods

to some other lazy-load methods like `getMessageBuilderFactory()`
* Fix parser tests to remove `messageBuilderFactory` tests since there is no activity for target components to lazy-load them
