JIRA: https://jira.spring.io/browse/INT-3614
The `extractPayload` is present in the namespace support for `<int-jms:inbound-channel-adapter>`,
but nor `JmsInboundChannelAdapterParser`, neither `JmsDestinationPollingSource` take care of that value.
To be consistent with `<int-jms:message-driven-channel-adapter>` and documentation, introduce that option for
`JmsDestinationPollingSource` and populate it from the `JmsInboundChannelAdapterParser`.
