One thing to be a little careful about if we merge these tunables
together, is what tunables are allowed to be changed while the migration
is running. The 'capabilities' are currently fixed once the migration
starts, but I know at least some of the tuneables people want to change
while things are going - and some care is needed with it since (as we
found with the xbzrle cache size) we get fun due to the use being in
a different thread.
