bundle: extend the format of --type to support version and compression
We had some basic undocumented support for uncompressed bundle2 support. We now
have an official extensible syntax to specify both format type and compression
(eg: bzip2-v2).
In practice, this changeset introduce the 'v1' and 'v2' identifier to make it
possible to combine format and compression. The default format is still 'v1'.
We'll care about picking 'v1' or 'v2' in regard with general delta in the next
changesets.
