Allow Override default network_data/vip yaml

With this change we are adding capability to create custom
baremetal environment specific yaml templates:-

* network_data.yaml
* vip_data.yaml

Above files will be created using the var `network_data_details` and
`network_vip_details` defined in downstream env_setting.yml(details
about env_setting.yml in [1])

Also, Updating `overcloud-deploy` role to parameterize the location of
network_data.yaml and vip_data.yaml file, this will help override the
default location.
