INT-3284: Address PR's comments
JIRA: https://jira.springsource.org/browse/INT-3287
* Fix package tangle (INT-3287)
* Apply `IntegrationConfigurationInitializer` for `MBeanExporterHelper`
* Previously, there was a separate `ChannelSecurityInterceptorBeanPostProcessor`
for each `ChannelSecurityInterceptor` whereas now, there is one `ChannelSecurityInterceptorBeanPostProcessor`
that processes all interceptors
INT-3284 Refactoring around config package tangle
Copy schemas, cleanup whitespace, update spring.schemas files,
update version in AbstractIntegrationNamespaceHandler.
For each schema compared the 2.2 version with the 3.0 version
(diff -w), ensuring the only difference is the import of
3.0 schemas (where appropriate) instead of 2.2.
Add 2.2 versions of module schemas.
JMX is already covered by an existing pull request.
INT-2536 Schema Check
Bump version for schema check in
AbstractIntegrationNamespaceHandler.
INT-2536 Remove Schema Versions
Some test config files had 2.1 versioned schemas.
@Ignore'd SimpleTcpNetOutboundGatewayTests#testOutboundClose() to avoid failure; this failure is correlated to the module name change, but hard to understand how it would be caused by it
