Change ironic jinja var for Cinder section

According to current logic when rendering ironic.conf
file "ironic" var is assigned either to "api" or "conductor"
map.jinja var depending on which component is enabled. However it was
found that in case both api and conductor are enabled "ironic"
var will be assigned to "api" var and will never be assigned to
"conductor" var. Since Cinder resides under ironic:conductor
in order to set its parameters the "ironic" var has been changed to
"conductor" var in Cinder section
