evolve: add an `--update` flag to `hg evolve` command
This patch adds a new `--update` flag which defaults to True. The update flag
updates the working directory to the head of evolved revisions after `hg evolve`
command.
This flag can be used to not update your working directory after `hg evolve`
which has been one of the biggest feature request from fig team at Google. To
not update your working directory, the user can do `hg evolve --no-update`.
If the working directory get obsoleted by evolve command, it will update to the
successor.
This patch also adds some basic tests for the flag introduced.
