    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
