ConcurrentHashMap implements `containsKey` with `get`. By removing a
redundant call to `containsKey`, we guarantee better performance in our
counter services.
The geek inside measured this with JMH, and found under 4 threads of
contention, throughput on this check was 40% higher in success case.

Previously, if there was a hierarchy of SpringApplications, the admin
MBean would report that the application was ready as soon as any
application in the hierarchy was ready. This could lead to a client
trying to query a property in the environment before it's available.
This commit updates the MBean registrar to that the MBean only reports
that the application is ready when the context that contains the
registrar has refreshed and fired its ApplicationReadyEvent.

Previously, the shutdown endpoint would spawn a new thread to perform
the shutdown but did not explicitly configure its thread context
class loader (TCCL). This mean that the new thread would use the
request thread's TCCL as its TCCL. This meant that a different TCCL
would be used compared to a shutdown triggered by the shutdown hook
and also caused problems with Tomcat's thread leak detection logic.
This commit updates the shutdown endpoint to explicitly configure the
TCCL of the shutdown thread to be the ClassLoader that loaded the
endpoint's class.

Commit 3ea84f9e1 has wrongly introduced a `@Primary` marker on
`IntegrationMBeanExporter` so any use of both Spring's JMX support
and Spring Integration's JMX support leads to an exception. This commit
makes sure to remove the unnecessary `@Primary`
Closes gh-6328
This commit makes sure to use `getAliasedStringArray` rather than
`getStringArray` as the latter does not work with ASM. While this will
probably be fixed in the core framework, this commit also adds dedicated
tests with ASM to ensure that the code works as expected.

Update WebRequestTraceFilter so that additional post processing can be
applied to traced request headers. The postProcessRequestHeaders method
can be used to remove or change map entries before they are returned.
Fixes gh-6309
Update MockDefinition to only call `Answers.get()` if a direct cast
isn't possible. This provides compatibility with Mockito 2.0 (currently
2.0.47-beta) without breaking support for Mockto 1.x.
Closes gh-6323
Previously, an entry had to be added to spring.factories using the
name of one of the @AutoConfigure… meta-annotations on the @…Test
annotation as the key. This indirection was unnecessarily complicated.
This commit simplifies things by allowing the name of the @…Test
annotation itself to be used as the key.
