##### SUMMARY
There is no real reason that `UnsafeProxy` needs to exist.  

We need to add unsafe bytes support, and by doing so within `UnsafeProxy` over complicates matters.

`wrap_var` should effectively take over the work that `UnsafeProxy` is doing, and then just rely on `wrap_var` directly using the proper `AnsibleUnsafe*` classes. Or callers can directly use `AnsibleUnsafe*` themselves when `wrap_var` isn't necessary.
