Valentin Rothberg 8489dc4345 move go module to v2
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].
