If a JtaTransactionManager is present, it is associated with the
auto-created JmsListenerContainerFactory. However, if no such transaction
manager is present, local transaction support is not enabled.

This gives a default situation where the message is acknowledged even
before the listener is invoked. We now make sure to turn on local JMS
transactions if no JtaTransactionManager is present.

Previously, JacksonHttpMessageConvertersConfiguration would configure a
general-purpose MappingJackson2HttpMessageConverter only if there was
no existing MappingJackson2HttpMessageConverter in the application
context. This was problematic when a
TypeConstrainedMappingJackson2HttpMessageConverter bean was present.
Such a bean is only capable of performing conversion for a specific
type, and therefore is no substitute for a general purpose converter,
yet its presence was causing the auto-configuration of a general
purpose converters to be turned off. This would leave Spring MVC’s
default converter being used for application/json requests which would
not honour the user’s Jackson configuration.

This commit enhances @ConditionalOnMissingBean so that the annotation
can be used to specify one or more types that should be ignored when
searching for beans. This allows the
TypeConstrainedMappingJackson2HttpMessageConverter beans that are
published by Spring Data REST to be ignored such that the
general-purpose MappingJackson2HttpMessageConverter is still
auto-configured.

Update MustacheViewResolver so that buildView() is called to create
the MustacheView. This sets fields such as `contentType` and allows us
to remove explicit setApplicationContext() and setServletContext()
calls.

GzipFilterProperties uses HttpMethod so GzipFilterAutoConfiguration,

There is a new spring.factories entry for
org.springframework.boot.actuate.autoconfigure.EndpointWebMvcConfiguration
which loads extra beans into the MVC config for the Actuator.
If the management context is a child context all the beans go in the
child (except the Spring Security filter still). A big bonus is that
you can add WebConfigurerAdapters to configure static resources etc.
A new component called ManagementContextResolver can be used to
locate the ApplicationContext for the MVC endpoints.
