With the advent of Podman 2.0.0 we crossed the magical barrier of go modules. While we were able to continue importing all packages inside of the project, the project could not be vendored anymore from the outside. Move the go module to new major version and change all imports to `github.com/containers/libpod/v2`. The renaming of the imports was done via `gomove` [1].
