Spring Integration Components should not use generated inner-bean names

• removing generated names for inner components
• instead use id of the enclosing adapter and append some suffix (e.g. ".adapter")
• This does not have to be configurable.

See the following commit that gives an alias to MessageHandlers within consuming endpoints...

The Stored Procedure components (JDBC Adapter) apply the following logic (example):

final AbstractBeanDefinition jpaExecutorBuilderBeanDefinition = storedProcExecutorBuilder.getBeanDefinition();
final String gatewayId = this.resolveId(element, builder.getRawBeanDefinition(), parserContext);
final String jpaExecutorBeanName = gatewayId + ".storedProcExecutor";

parserContext.registerBeanComponent(new BeanComponentDefinition(jpaExecutorBuilderBeanDefinition, jpaExecutorBeanName));

Maybe there is a way to expand upon IntegrationNamespaceUtilsgenerateAlias(). We probably should also considering to implement this in a type-safe manner...e.g. defining an Enum for common suffixes.
