Apex: Removes nosdn from verify

Apex: Removes nosdn from verify

Since we now have gate jobs in order to verify functionality specific to
a scenario, we can eliminate running 2 pre-gate verify deploys with
nosdn and odl_l3.  The consensus from Apex team is that we gain little
validation with nosdn in comparison to odl_l3, so we can remove nosdn
and then trigger it as a specific gate job if we need to validate its
functionality.
