systemd: Always create the systemd unit files

Commit 5edae54 introduced the usage of systemd in Devstack. This allowed
the transition away from 'screen'. Systemd needs "user unit files" to
describe the services. Currently, those unit files get only created when
an openstack service (n-cpu, c-sch, g-api, ...) is in the list of enabled
services (`ENABLED_SERVICES`). This means, when Devstack is fully stacked,
there is no way to start the systemd unit of an openstack service which
is *not* in that list.

This commit changes that behavior, and creates the systemd unit files
independently of the list ENABLED_SERVICES. This means, when Devstack
is fully stacked, I can start a systemd unit of an openstack service which
wasn't in the ENABLED_SERVICES list. This allows more flexible lifecycle
management of openstack services in the gate, which is useful for tests
which test components which are not in the "default configuration" (e.g.
the "nova-serialproxy" service).

The `clean.sh` script purges all traces of systemd user unit files created
by devstack.
