Advanced networking is missing in 0.5

[Stan Lagun]

Networking options that ware available in Murano 0.4 doesn't work in 0.5. Neutron resources are not created

[Timur Nurlygayanov (tnurlygayanov)]

Need to implement the advanced networking for 0.5. The priority was changed to Critical because without this option Murano will work really strange.

    Removed 'Networking' section

    Old (0.4.x style) section, containing networking parameters of environment, is never processed
    by the engine, so it has been removed from the environment generation logic.

    New (0.5-compatible) block of network setting will be added at murano-api side.

    This is part of Advanced Networking commit series, yet is independent from all others.

    Added NetworkExplorer engine object class

    Added a NetworkExplorer class (maps to io.murano.system.NetworkExplorer) to explore
    the Network Environment of an active tenant.
    The class is able to locate the default router (if present) and allocate available
    CIDR range for the selected router. The latter requires some configuration options
    (for proper CIDR segmentation)

    This commit adds python-neutronclient to the requirements, as NetworkExplorer has
    to directly interact with Neutron

    This classes is a crucial part of AdvancedNetworking implementation

    Added MuranoPL infrastructure for advanced networking scenarios

    Base class 'Network' (io.murano.resources.Network) was added to core package.
    This class is an abstract class for network interaction, to be inherited by
    engine-specific implementations.

    'Environment' class got a 'defaultNetworks' input parameter, containing two
    different instances of Network class for two initially supported networking use-cases:
    'environment' for a topology when each environment has an isolated network
    'flat' for a single network per multiple environments

    'Instance' class got a 'networks' input parameter with a default value.
    This is a composite parameter indicating which networks the instance should join
    If 'useEnvironmentNetwork' is set to 'true' the instance should join an
    isolated network of current environment
    if 'useFlatNetwork' is set to 'true' the instance should join a single
    shared network
    Both values may be enabled, so the instance will join both networks.
    'customNetworks' field of the same data structure may be used to specify custom
    network resources to join

    Same commit includes a temporary workaround for bug #1313694
    The workaround is needed to properly use default of 'networks' field

    The actual implementation of io.murano.resources.Network class should
    be done in a separate package, which should be added to app-incubator repo

    Implemented AdvNetworking scenarios via Neutron

    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.
