Resolve slow fact gathering when seed SNAT is off

Browse Source 
Stop configuring the seed host as gateway when seed SNAT is disabled
(which is the default since Xena), otherwise overcloud hosts may take a
long time to gather facts until their network configuration is applied
(probably because DNS servers are thought to be reachable until the
gateway is changed or removed).

upgrade:
- |
If the admin network does not have a gateway defined and
``seed_enable_snat`` is ``false``, which is the default, overcloud hosts
will not have a default gateway immediately after provisioning anymore. A
default gateway on another network can still be applied during the host
configuration step.
fixes:
- |
Fixes slow fact gathering in some environments by not configuring the seed
host as the initial default gateway for overcloud hosts when
``seed_enable_snat`` is ``false``, which is the default.
