Add a function to check the cacert file

1. Currently it won't pass the cacert file to other containers if the
   OS_AUTH_URL is http not https.
2. However, even though the OS_AUTH_URL is http, it still needs cacert file
   somewhere for Functest and Rally.
3. This problem is found on Fuel Euphrates.
4. Add a function to check whether the cacert file exists.
5. If exists, pass it to testing project containers.
