INTEXT-197: Lifecycle attrs for s3-outbound-c-a

JIRA: https://jira.spring.io/browse/INTEXT-197

* Modified the `org/springframework/integration/aws/config/xml/spring-integration-aws-1.0.xsd` to add `channelAdapterAttributes` to expose
`phase` attribute in `s3 outbound adapter`.
* Modified `AmazonS3OutboundChannelAdapterParserTests` - Added Unit Test Class to test the `channelAdapterAttributes`.
* Modified `s3-valid-outbound-cases.xml` - Added separate definition `withChannelAdapterAttributes` for phase attribute.
