bundle2: add an exchange.getbundle function
This function can return a `HG10` or `HG20` bundle. It uses the `bundlecaps`
parameters to decides which one to return.
This is a distinct function from `changegroup.getbundle` for two reasons. First
the APIs of `bundle10` and `bundle20` are not compatible yet. The two functions
may be reunited in the future. Second `exchange.getbundle` will grow parameters
for all kinds of data (phases, obsmarkers, ...) so it's better to keep the
changegroup generation in its own function for now.
This function will be used it in the next changesets.
