Update appendix example to use the more common `/var/log` folder rather
than `/var/logs`.

Previously, the VcapApplicationListener would discard any service
credential value that wasn't a String, Number, Map, Collection, or
null.  This was particularly a problem for services that exposed a
value as a JSON boolean.  This change takes booleans in the credential
payload into account, converting them to Strings so that they will
pass through the properties system properly.  There's no real downside
to this as Spring will coerce them back into Booleans if needed, by
the application.

AmqpAdmin does not require a CachingConnectionFactory. Using the more

Previously, spring.groovy.template.configuration.* was mapped onto both
GroovyTemplateProperties.configuration and GroovyMarkupConfigurer. The
former being a Map and the latter being specific type with getters and
setters. This clash caused problems with the IDE support.

GroovyTemplateProperties.configuration appeared to be dead code so it
was removed in 326bdf29. Unfortunately this broke the use of
spring.groovy.template.configuration.* properties as
GroovyTemplateProperties uses a prefix of spring.groovy.template and it
no longer had a configuration property.

This commit addresses the problem by updating GroovyTemplateProperties
to ignore unknown fields. This allows
spring.groovy.template.configuration.* properties to be used and bound
to GroovyMarkupConfigurer without reintroducing the clash which prompted
the initial change.

The build currently fails intermittently when an external container,
usually TomEE or Wildfly, fails to start within the default timeout
period of two minutes. This commit updates the timeout to 5 minutes for
all containers (Tomcat, TomEE and Wildfly) in the hope that it will
help to stabilise the CI build.

The JMS MessageListenerContainer supports the PlatformTransactionManager
abstraction with either a `JmsTransactionManager` for local transactions
or `JtaTransactionManager` for distributed transactions. The former is
kind of deprecated (`setTransacted` should be used instead). In any case,
any other `PlatformTransactionManager` implementation is not supported.

Update JmsAnnotationDrivenConfiguration to only associated a JTA
transaction manager, if any.

Only affects the default AuthenticationManagerBuilder (so when users
are not overriding the default global user details). Makes the

AuthenticationManagerBuilder.inMemoryAuthentication() as a
shared object in the HttpSecurity.

Do not rely on the packaging type to figure out what the extension of the
main artifact will be. So far, using `jar` and `war` packaging for `.jar`
and `.war` files worked by chance.

We know retrieve the actual extension as provided by Maven's
`ArtifactHandler`.
