Subject: [PATCH] Include aliases in the fqdns grains
Add UT for "is_fqdn"
Add "is_fqdn" check to the network utils
Bugfix: include FQDNs aliases
Deprecate UnitTest assertion in favour of built-in assert keyword
Add UT for fqdns aliases
Leverage cached interfaces, if any.
Implement network.fqdns module function (bsc#1134860) (#172)
* Duplicate fqdns logic in module.network
* Move _get_interfaces to utils.network
* Reuse network.fqdns in grains.core.fqdns
* Return empty list when fqdns grains is disabled
