* pr/6579:
  Polish audit event endpoint support
  Improve MBean without backing Endpoint support
  Add MVC and JMX endpoints to retrieve audit events
  Add JMX without backing `Endpoint` support

Closes gh-6579

Improve support for MBeans without a backing endpoint by introducing
a `JmxEndpoint` interface. The `JmxEndpoint` is intentionally
similar in design to the `MvcEndpoint` from the `mvc` package and
allows for completely custom JMX beans that are not backed by any
real actuator `Endpoint`.

The `AuditEventsMBean` has been refactored to use the new interface and
has been renamed to `AuditEventsJmxEndpoint`.

See gh-6579

Add MVC and JMX specific endpoints that allow audit events to be
retrieved.

See gh-6579

Decompose `EndpointMBean` to improve support for JMX endpoints without
a backing `Endpoint`.

See gh-6579

Update `MvcEndpointSecurityInterceptor` and
`CloudFoundrySecurityInterceptor` to allow OPTIONS requests to be
processed.

  Add force-stop to launch.script usage

See gh-6223
Closes gh-7787

Update `ImportAutoConfigurationImportSelector` to ignore excludes for
classes that aren't loaded. Since the import classes for tests tend to
be much more limited, the exception isn't really helpful.

Closes gh-6809

Update LiveReloadServerTests which seems to be failing intermittently
on Travis.

Update `@ImportAutoConfiguration` with support for an exclude attribute
that works in a similar way to `@EnableAutoConfiguration`.

Also update existing `@Test...` annotation with exclude attribute
aliases.

Fixes gh-6809

  Add `force-stop` support to launch script

Update the embedded launch script to support `force-stop`.

implemented using a lambda.

* pr/7786:
  Remove a nested TransactionProperties

Remove a few nested `TransactionProperties` that should have been
deleted in commit f22744c7.

See gh-7561
Closes gh-7786

Refine commit 1e9e1b04 since it unfortunately had the side-effect of
disabling logging when a valid `log4j2.xml` file was found.

The updated code uses a similar technique but instead of accepting
'*' as a file type it now looks for `.springboot` (which it finds
because we ship a `log4j2.springboot` file in out JAR.

Rather than exiting Log4J2's `ConfigurationFactory.Factory`
`getConfiguration` method early, our `SpringBootConfigurationFactory`
is now only triggered on the last call to `getConfiguration`.
