Don't assume environment.d is always under /tmp/in_target.d. This makes dib-run-parts more flexible, and less specific to diskimage-builder. For instance, dib-run-parts is already used by os-refresh-config, but /tmp/in_target.d/environment.d is never going to exist when it's called by os-refresh-config. This is useful b/c elements can now install os-refresh-config scripts under /opt/stack/os-config-refresh/environment.d to influence how further scripts are run. Specifically, the OpenSuse packages prepend the OpenStack user accounts with "openstack-". Instead of checking for which users exists with an if/else in all the os-refresh-config scripts that need to do user related things, we can just update the scripts to use $NOVA_USER, etc. The OpenSuse element can then install a file under /opt/stack/os-config-refresh/environment.d to set NOVA_USER to openstack-nova. We could have files that declare defaults as well within each specific element, or just set a default variable at the top of each os-refresh-config script.
