Previously, you would do either:
`msg:set_meta('queue', 'smart.host.domain')`
or
`msg:set_meta('queue', '[10.0.0.1]')`
to override the effective domain for a message and cause it to be routed
to somewhere other than the recipient domain.
That was OK for basic smart hosting, but limiting when you wanted to use
multiple candidate hosts.
This commit expands the queue config `protocol` field to support
specifying an explicit list of MX hosts that should be used instead.
The integration tests have been migrated away from the old style to this
new style.
While adding plumbing for this, I uncovered an inconsistency between the
queue name generated for the ready queue and the name used by suspension
handling. The inconsistency was introduced in
0842a0fc8b and related work. This commit
resolves it.
