Work around brittle annotation scanning in Mojarra

FacesListener in Mojarra 2.2.12 (used in Glassfish 4.1.1) is a
ServletContainerInitializer that’s annotated to handle types annotated
with javax.annotation.Resource.
OAuth2RestOperationsConfiguration.SessionScopedConfiguration is one such
class. This leads to com.sun.faces.config.DelegatingAnnotationProvider
calling getAnnotations on SessionScopedConfiguration.class. This fails
with a java.lang.ArrayStoreException due to SessionScopedConfiguration
being annotated with @ConditionalOnBean(OAuth2ClientConfiguration) and
OAuth2ClientConfiguration not being on the classpath.
DelegatingAnnotationProvider currently catches NoClassDefFoundErrors
thrown during its annotation processing. It needs to be made more
robust so that it also copes with an ArrayStoreException, in a similar
way to how org.glassfish.apf.impl.AnnotationProcessorImpl was updated to
fix GLASSFISH-21265 [1]. I’ve opened an issue to this effect [2].

In the meantime, we can work around the brittleness in
DelegatingAnnotationProvider by restructuring
SessionScopedConfiguration. This commit moves the use of @Resource into
a nested inner class, ClientContextConfiguration, while leaving the use
of @ConditionalOnBean on SessionScopedConfiguration. This means that it
is now ClientContextConfiguration that is passed to FacesListener and
processed by DelegatingAnnotationProcessor, thereby avoiding exposing
it to the @ConditionalOnBean annotation that it does not handle
gracefully. A Glassfish-based deployment test has also been added to
verify the fix.
