ospfd: Running config to display VRF aware OSPF

show running-config to display VRF aware ospf instances
even if VRF is not active. This will allow the user to
configured ospf instances configurations even if VRF is not
active. 'show ip ospf vrf all' does not display until VRF
is active.

Ticket:CM-18949
Reviewed By:
Testing Done:
Configure non-default vrf aware ospfs with prior vrf devices
configured.
All vrf aware 'router ospf' displayed in running-configuration.
Disable one of the vrf device still all vrf aware 'router ospf'
displayed in running-config, but 'show ip ospf vrf all' does
not display for which VRF is not active.
