Unpack cni_plugins, crictl & etcd to folders in /opt and use symlinks
Browse files Browse the repository at this point in the history 
Makes the installation of cni_plugins, crictl & etcd similar to the way
the main k8s binaries are installed. The archives are unpacked to folders
in /opt and symlinked to /usr/local/bin . The target folder is unique
per version, making it possible to update these components.

Fixes #95.
