Description

The new addressing scheme defines the following reliability modes.

unreliable: there may be duplicate messages, and there may also be missing messages
at-most-once: there may be missing messages, but there will be no duplicate messages
at-least-once: there may be duplicate messages, but there will be no missing messages
exactly-once: there will be no missing or duplicate messages

The mapping to the 0-10 protocol is as follows.

1. For at-most-once (and unreliable) we need to use accept-mode=none.
2. For at-least-once we use non auto-delete (i.e. auto-delete=false), and accept-mode=explicit
3. exactly-once is not yet supported.

The default reliability mode is at-least-once.
