Generate a new private RSA key. This factory function can be used to
generate a new host key or authentication key.
@param bits: number of bits the generated key should be.
@type bits: int
@param progress_func: an optional function to call at key points in
key generation (used by C{pyCrypto.PublicKey}).
@type progress_func: function
@return: new private key
@rtype: L{RSAKey}
