internals: document bundle2 format

It seems like a good idea to have thorough documentation of the bundle2

fully capture the semantics of each capability and part. But a start
is better than nothing, which was pretty much where we were before.

  $ hg co 0
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
