bundle2: add a devel option controling bundle version used for exchange
We need an official way to force bundle1 to be used in test. We introduce a new
option 'devel.legacy.exchange' to control this. When specified, this option
will control the list of bundle version Mercurial consider when exchanging with
a peer. Current valid value are 'bundle1' and 'bundle2'.
Using this option in all tests will allow us to remove the
'experimental.bundle2-exp' option. We will simplify the code once the
experimental option is dropped.
