- Per-binding properties defined in `BindingProperties` need to hold the binder specific configurations needed when binding producer/consumers.
Previously, these were added in `ChannelBindingServiceProperties` as producer/consumer properties. Since these configuration properties are for
per-binding based on the input/output (consumer/producer) channel being bound it is better to move these properties into `BindingProperties`.
- Add some of the supported producer/consumer properties into BindingProperties
- This fixes#256
Rename CommonBinderProperties -> BinderPropertyKeys
Rename class AbstractBinderPropertiesAccessor.java -> AbstractBindingPropertiesAccessor.java
- Add `MessageChannelConfigurer` that any class that configures the message channel would implement
- Have `message-converter` and `message-history-tracking` configurer implement this interface
- Autowire all available configurers and use them to configure the message channel
- For the message history tracking
- add `channel-binding` properties as part of message header along with `timestamp`
- Introduce CompositeMessageChannelConfigurer
Remove field injection of messageChannelConfigurer
Add tests for message track history configurer
Add content-type configurer test
Address review comments
- Add `toString` to BindingProperties
- Add test case to depict producer/consumer properties
Remove processor channels from tests
