Timeout manager
The timeout manager is removed from core which makes timeout manager backwards compatibility mode obsolete. If backwards compatibility mode was enabled these APIs must be removed.
WithPeekDelay replaced by QueuePeekerOptions
In version 6 of the transport it was possible to define the message peek delay using the WithPeekDelay configuration option. The configuration setting has been moved to a more generic QueuePeekerOptions that allows to configure also other parameters related to message peeking.
