Deprecate manila-all command

/usr/local/bin/manila-all purports to start all the manila
services within a single process.  We should deprecate this
command since to do this in production would be a very bad
idea - completely un-"cloudy" - and we don't even do it in
devstack.

Implements blueprint deprecate-manila-all
