Instead of recreating a dispatcher in the server
and executor objects use a common dispatcher that
is shared between them. It will dispatch based on
the message type received into a provided dict of
dispatch handler callbacks.
It also can generically requeue messages and can
reject messages if they are missing key required
message properties ('type' in the current case).
