Switches to internal network by default + update Ubuntu image name
Closes #3 (closed)
Switches to the internal network by default.
Also, fixes the default OpenStack image to the currently available Ubuntu version
During the maintenance period on Monday, 14 Oct 2024, all new projects will no longer create a container registry as part of the project area. Already existing projects will be unaffected at this time. Instead, users should utilize the official ORNL container registries at camden.ornl.gov (internal/moderate) and savannah.ornl.gov (external/low). Please see ORNL Today article for more info.
