I assume we will document this "UNIX wizard"-ish format internally (that is, in the code) before shipping 3.13 :) |

Message container annotation keys are stored on disk.
By shortening them we save 95 - 58 = 37 bytes per message.
```
1> byte_size(term_to_binary(#{exchange => <<>>, routing_keys => [<<"my-key">>], durable => true, priority => 3, timestamp => 1000})).
95
2> byte_size(term_to_binary(#{x => <<>>, rk => [<<"my-key">>], d => true, p => 3, ts => 1000})).
58
```
This should somewhat reduce disk I/O and disk space.
Prevent key 'durable' with value 'undefined' being added to the mc annotations, for example when the durable field was not set, but another AMQP 1.0 header field was set.

* Ensure durable is a boolean

mc annotations, for example when the durable field was not set, but
another AMQP 1.0 header field was set.
