This commit makes sure that the Spring `Validator` used by the MVC
layer doesn't expose a JSR-303 contract, if any.

The default implementation of the `mvcValidator` is
`LocalValidatorFactoryBean`. While this object is exposed as a Spring
`Validator` only, its runtime capabilities expose that contract as well
as the standard `Validator` and `ValidatorFactory` ones.

Concretely, if an auto-configuration is checking if a
`javax.validation.Validator` bean is missing, the condition will match
since we only know about "advertized types": beans haven't been created
yet so we can't inspect their runtime capabilities. Since the condition
match, we will auto-configure a bean. At runtime though, we're no longer
ale to inject a `javax.validation.Validator` by type since two candidates
are available.

This commit introduces `SpringValidatorAdapterWrapper`, a wrapper class
on any `SpringValidatorAdapter` (`LocalValidatorFactoryBean` being one of
the available implementations) that only exposes the Spring contract.

Also, if a `javax.validation.Validator` bean is available, we will use it
for the MVC layer, rather than creating a new one.

In Logback 1.1.10, the logback-classic module contains a
META-INF/services/javax.servlet.ServletContainerInitializer file that
contains a comment. This triggers a bug in Wildfly 8 [1] that has been
fixed [2] in Wildfly 9 and later. As a result, this commit also
updates our Wildfly deployment test to use 9.0.2 rather than 8.2.0.

Previously, @SpyBean's name attribute was not used when determining
the name of the bean to spy upon. When there were multiple candidates,
none of which were primary, this would lead to a failure to find the
bean to spy upon. This behaviour is also inconsistent with @MockBean
which does use the name attribute to identify the bean to mock.

This commit updates MockitoPostProcessor to use the name attribute,
when set, to identify the bean that should be spied upon. For
consistency with @MockBean it is always used when set. When not set
the previous logic will continue to be used.

Previously, the custom layout sample could only be built successfully
if spring-boot-dependencies had be installed locally, making its
effective pom available in the local Maven cache.

This commit updates the sample's tests to look at its own pom to
determine the version of Spring Boot that should be used in the
Gradle tests.
