[type/__dma_auth] Drop --server parameter

Currently, dma does not differentiate between login users on the SMTP server.
It will pick whatever entry it finds first
(https://github.com/corecode/dma/blob/v0.13/net.c#L531).
As a result, the --server parameter only adds confusion.

 This cdist type allows you to set up credentials to log in to remote SMTP
 servers.
 
+NB: dma currently (v0.13) does not differentiate between users on a host.
+    It will use whatever user it finds in the ``auth.conf`` first.
+    Thus, this type will use the ``__object_id`` as the host specifier.
