import: move tryone closure in cmdutil
We extract the `tryone` function into the `cmdutil` module. A lot of the command
context have to be passed to the utility function, but having and explicit
declaration will allow extension to wrap it. This will allows use to make
changeset evolution related experiment in dedicated extension.
Improving the API of this function is noble goal but outside of the scope of
this patches.
