This commit adds buildah tool support for OCI and Docker types. It
requires buildah and skopeo to be installed in the host. The use of
umoci (kept as default choice) or buildah is configured using the
runtime configuration file; consider the following structure:
```
oci:
- archive_tool: buildah
```
