INT-3705: Improve Messaging Annotations handling

JIRA: https://jira.spring.io/browse/INT-3705

* Add validation for annotation attributes which must be populated directly on the `MessageHandler` `@Bean` using setters
* Add `sendTimeout()` annotation attribute for all Messaging Annotations
* Remove `DEFAULT_SEND_TIMEOUT = 1000L` from `AbstractCorrelatingMessageHandler` to make its component consistent with all other
`AbstractMessageProducingHandler` implementation.
* Fix XSD docs and Reference Manual to say that default `send-timeout` for `AbstractMessageProducingHandler` components is `-1`, not `one second`
* Make all Messaging Annotations attributes as `String` to allow to configure through the Property Placeholder options
* Fix a couple of typos
