netconfig task doesn't support hiera override

[Nikita Koshikov]

In netconfig.pp task we have code:

$network_scheme = hiera('network_scheme')

If we create override for network_scheme hash this will break deployment.

valid for fuel 7.0

    Use hiera_hash() instead hiera() for some hashes.

    The following hiera lookups should always be hiera_hash:
    * network_scheme

    Removed array lookup for nameservers

    dns_nameservers is now a normal priority lookup, not array
    Removed unused novanetwork_parameters lookup
