Fix to use . to source script files

Adhering to coding conventions. Refer to ``Code conventions`` at
https://docs.openstack.org/contributor-guide/ for details.
When you have to source a script file, for example, a credentials file
to gain access to user-only or admin-only CLI commands, use . instead of source.
