[pve-devel] [PATCH storage v4 13/15] allow .tar container templates

[Filip Schauer <f.schauer@proxmox.com>]

This is needed for OCI container images bundled as tar files, as
generated by `docker save`. OCI images do not need additional
compression, since the content is usually compressed already.

Changed since v2:
* Modify VZTMPL_EXT_RE_1 regex to put "tar" into capture group when
  matching on a .tar file.
