Implement secure deserialize function

[Adrian Otto]

The deserialize function that swagger uses includes the usage of eval. It is posible to completely destroy a system using eval,
so eval usage is not recommended. Our bandit non-voting gate will reject eval usage. stackoverflow recommends using
ast.literal_eval, but we must create python objects in some casess, with ast.literal_eval will not do. Instead write a new
implementation of deserialize which is secure.

The python k8s library is busted without fixing this - changing importance to high.

This will require a backport when it has been verified.

    Avoid to use eval in pythonk8sclient

    The deserialize function that swagger uses includes the usage of
    eval. It is posible to completely destroy a system using eval, so
    eval usage is removed in this patch. This fixes the failure of bandit
    non-voting gate.
