Added a new package ( io.murano.lib.networks.Neutron) to handle networking via Neutron The package introduces a class 'NewNetwork' (io.murano.lib.networks.neutron.NewNetwork) This class is capable of the following: - Create a new Network (L2 segment) - Use NetworkExplorer class to allocate an available CIDR - Create a new Subnet (L3 segment) in the created Network with the allocated CIDR - Use NetworkExplorer class to locate an available router - Use NetworkExplorer class to detect the default DNS nameserver - Uplink the created subnet to the located router Also, as this class extends io.murano.resources.Network, it implements the addHostToNetwork method The implementation creates a Neutron Port and connects that port to a created network and intance This commit also modifies the environment-creation logic of the API, allowing to add default networks to the Environment object. This is a temporary solution: in future the instantiation of this object(s) should be done in MuranoPL This commit concludes the minimum set of functionality needed to implement AdvancedNetworking in 0.4.x feature set.
