implement implement IPersistTimeoutsV2 interface

[timbussmann]

Who's affected

You might be affected if you are using one of the following transport configurations:

• RabbitMQ transport
• Azure transport
• MSMQ or SQL transport with distributed transactions (DTC) disabled.

and you are using timeouts or deferred messages (e.g. Bus.Defer(...))

Symptoms

When experiencing connectivity issues with the transport there's a chance that a due timeout/deferred message is lost. Therefore the message will never arrive.

What to do if you are affected

We highly recommend to update to the latest patch versions of your NServiceBus and optional persistence and transport packages. For more details see issue #2885

Connects to Particular/NServiceBus#2885

@SzymonPobiega @andreasohlund please review. I optimized the TryRemove (from the V2 interface) to directly use a DELETE without fetching the row first.

Looks good!
