This isn't something built into systemctl itself, but rather in the
"/usr/bin/service" wrapper and in initscripts functions generally:

e.g. in the "initscripts" git: git://git.fedorahosted.org/initscripts.git

[colin at jimmy initscripts (master)]$ git grep SYSTEMCTL_IGNORE_DEPENDENCIES
initscripts.spec:- /sbin/service: honor SYSTEMCTL_IGNORE_DEPENDENCIES
(<lennart at poettering.net>)
rc.d/init.d/functions:        if [ -n "$SYSTEMCTL_IGNORE_DEPENDENCIES" ]
; then
service:       export SYSTEMCTL_IGNORE_DEPENDENCIES=1
service:   env -i PATH="$PATH" TERM="$TERM"
SYSTEMCTL_IGNORE_DEPENDENCIES=${SYSTEMCTL_IGNORE_DEPENDENCIES}
SYSTEMCTL_SKIP_REDIRECT=${SYSTEMCTL_SKIP_REDIRECT} "${SERVICEDIR}/${SERVICE
service:   env -i PATH="$PATH" TERM="$TERM"
SYSTEMCTL_IGNORE_DEPENDENCIES=${SYSTEMCTL_IGNORE_DEPENDENCIES}
SYSTEMCTL_SKIP_REDIRECT=${SYSTEMCTL_SKIP_REDIRECT} "${ACTIONDIR}/${SERVICE}
