Not obvious how to juju run commands which have their own arguments

[James Troup]

'juju help run' says:

| usage: juju run [options] <commands>

So I try:

 | $ /srv/juju-dist/2.0.0/usr/bin/juju run --application=os-room1,os-room2,os-room3 hostname -f
 | error: flag provided but not defined: -f
 | $

Weird nomenclature, but OK. Let's try the standard "stop parsing
command line options from here":

| $ /srv/juju-dist/2.0.0/usr/bin/juju run --application=os-room1,os-room2,os-room3 -- hostname -f
| error: unrecognized args: ["-f"]
| $

So either, juju should respect '--' or the help text should make it
more obvious how to run commands with 'juju run' which include command
line options, e.g. by putting the string inside quotes.

FWIW, you can do this:

    juju run --application=os-room1,os-room2,os-room3 'hostname -f'

But that's dumb, and we should support multiple args. I'll fix that.
