Roman Khimov 5d5455312a rpcclient: add policy package for the PolicyContract contract
And test it with the RPC server.

Notice that getters still return int64 instead of *big.Int, that's because
these values are very limited and technically could even fit into an int (but
that seems to be too dangerous to use for long-term compatibility).
