Add the `allow_interactive_auth` and `no_autostart` attributes to `dbus_proxy`

The following discussion from !554 should be addressed:

• [ ] @zeenix started a discussion:

  Not for this MR but it'd be useful to also have these 2 new attributes on the whole proxy itself. The no_reply is typically a method call's policy (i-e declared by service) but these new attributes are client polices and in my experience, typically decided on a more global level than individual method calls.

@benferse I was actually hoping you'd be looking into this after !554 merge. ;)
