Query prefixes once for all hosts

Browse source 
And group them into vrf_prefixes for VLAN networks and bgp_prefixes for
servers plugged directly into fabric.

This should reduce the number of queries to NetBox when configuring
firewalls and exit switches. Not sure but I think set_fact helps to
avoid queries (as opposed to setting group_vars).
