JIRA: https://jira.springsource.org/browse/INT-3017

* Add parsers tests and integration tests
* Polishing Redis XSD
* Fix `JmsMessageDrivenEndpointParser` `LifeCycle` attributes
* Catch `RedisSystemException` after `this.boundListOperations.rightPop`.
It maybe an exception about 'connection closed'.
If the `RedisQueueMessageDrivenEndpoint` is 'active' this exception is rethrown,
otherwise just logged under error category.
* Add Redis queue components docs
