#10 Add SSL support to RPC protocol

[Tim Yates]

We need to reintroduce support for running the backend<-->frontend RPC service over SSL. This is already available for Thrift in Java, but isn't implemented in the Python library yet. It should be trivial to make this work (using Python's SSL socket support) until Thrift supports it.

[Stephen Lee]

It seems this is now supported in python with TSSLSocket and TSSLServerSocket
