Pass channel Config to PublisherDecorator and SubscriberDecorator

[ozangunalp]

Allow decorators to access the connector channel configuration

Also refactors PausableChannelDecorator to read the config directly from the passed channelConfig instead of pre-registering configurations, making it stateless and removing DefaultPausableChannelConfiguration.

Resolves #1969
