"network_create_args" dict for Network context looks strange for me and includes information for one specific tenant

    [Context] Fix side effect changes of context config

    Since context configuration passed to Context.__init__() is
    a mutable type (dict or list), sometimes we have unexpected
    changes done by unpredictable code (for example, in wrappers).

    This patch uses types `common.utils.LockedDict' and `tuple'
    for locking this data from further changes.

    Also there was missing unit test for Context.__init__()
    with DEFAULT_CONFIG set - this unit test is added.
