Integration tests are not able to run in an environment with SSL enabled

[Edmond Kotowski]

When runnning ./redstack int-tests in an environment with SSL enabled the tests will raise an exception:

SSLError: [Errno 1] _ssl.c:510: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed

Fix is to add a cacert variable on the test configuration and to set the cacert constructor parameter when creating the nova client.

    Allow int tests to run in SSL environment

    - int tests would raise an SSLError because
    we had no way to set the cacert when creating the
    nova client.
    - Added "cacert" parameter on the integration test
    config file.
    - Setting the cacert parameter on nova_client.Client
    constructor in create_nova_client method.
    - Defaulting cacert to None if none specified.
