Hi,

[ Reason ]
I discover that when running daemons with the queue manager
option, they create a file under /dev/shm that depends on the
process name, unless it is overritten by a config value. As
OpenStack API all run under uwsgi, the process name is the same
and clashes between services.

I've added a OS_OSLO_MESSAGING_RABBIT__PROCESSNAME environment
var at startup of all daemons, which is equivalent to set:

[oslo_messaging_rabbit]
processname=<something>

this way, this avoids multiple daemons using the same qmanager
file.

As I wanted things to be unified, I have set this env var for
all daemons, even if it doesn't change the current behavior
(ie: it used to use argv[0] which is the same as what I've set,
except for uwsgi API where it was really mandatory).

Also, for Neutron, you'll see 2 backported patches as bugfixes.
You may reply for Neutron specifically separately.

[ Impact ]
It would otherwise be impossible for OpenStack users to run
multiple API servers from different OpenStack project on the
same host, if activating the RabbitMQ queue manager.

[ Tests ]
I manually tested the fix.

[ Risks ]
Not much risk: it's just an env var per daemon.

[ Checklist ]
[x] all changes are documented in the d/changelog
[x] I reviewed all changes and I approve them
[x] attach debdiff against the package in testing
