run: introduce timer support option
Support timer options --on-active=, --on-boot=, --on-startup=, --on-unit-active=, --on-unit-inactive=, --on-calendar=. Each options corresponding with OnActiveSec=, OnBootSec=, OnStartupSec=, OnUnitActiveSec=, OnUnitInactiveSec=, OnCalendar= of timer respectively. And OnCalendar= and WakeSystem= supported by --timer-property= option like --property= of systemd-run. And if --unit= option and timer options are specified the command can be omitted. In this case, systemd-run assumes the target service is already loaded. And just try to generate transient timer unit only.
