Make the transport aware for how long (at minimum) the message should be kept alive.

F.e. when extending SQS visibility timeout, you need to pass the visibility timeout (seconds) as parameter. If you pass a value which is less than alarm interval, SQS would resend the message too early. By making the transport aware of when the next keepalive call will happen we'll be able to do some assertions/clamping to improve DX.

This is a prerequisite for #58483.
