These options weren't settable so far for transient units, because I was
too lazy to make them settable. ;-)

I have added this in now:

http://cgit.freedesktop.org/systemd/systemd/commit/?id=c7040b5d1c2c148f12b6a5eef3dfce1661805131

Which should make them available via the bus for transient units. If you
need other props like this, just let me know and I'll add them too...

RemainAfterExit=no is already available?
