Add possibility to give Openstack creds file to the docker container

If the file is given through a docker volume, it will not use
fetch_os_creds.sh, it will source it directly.

Usage:
 Add the following to the docker command line:
    -v $(pwd)/<your_local_creds_file>:/home/opnfv/functest/conf/openstack.creds
