Move spack package to repo; setup tests
Set up the spack package as a repo that can be added to an existing spack instance. Add a single test to make sure this repo can be added to a spack instance and that ContainerBuilder can be built correctly.
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.
