recover: add a --[no-]verify flag
For trivial cases, the cost of the verify run after `hg recover` is getting in
the way. In addition for very large repositories, the cost is simply too high
to be paid, making `hg recover` an unusable commands.
We introduce a --verify flag, set by default. If is automatically associated
with a --no-verify flag that one can use to skip the verify step.
We might consider changing the default behavior in the future. However this is
out of scope for this series.
