Rule creation with congress_noauth fails

 "" around rule get removed when we try to interpret them as positional parameters in bash

Need to escape double-quotes

See the difference:

./congress_noauth policy rule create test_policy1 "a(x) :- b(x)"
openstack --os-token foo --os-url http://127.0.0.1:1789 congress policy rule create test_policy1 a(x) :- b(x)

./congress_noauth policy rule create test_policy1 "\"a(x) :- b(x)\""
openstack --os-token foo --os-url http://127.0.0.1:1789 congress policy rule create test_policy1 "a(x) :- b(x)"

Executing command in this manner work:

openstack --os-token foo --os-url http://127.0.0.1:1789
(openstack) congress policy rule create test_policy1 "a(x) :- b(x)"
