[pve-devel] [PATCH container v2] Fix #2124: Add support for zstd

[Alwin Antreich]

This seems to me as a totally new try, since so much time has passed. :)

Zstandard (zstd) [0] is a data compression algorithm, in addition to gzip,
lzo for our backup/restore.

v1 -> v2:
    * factored out the decompressor info first, as Thomas suggested
    * made the regex pattern of backup files more compact, easier to
      read (hopefully)
    * less code changes for container restores

Thanks for any comment or suggestion in advance.
