locarepo: remove the `push` method

All the logic of this function is in the exchange.push function for some time.
We just stop calling `localrepo.push` in `command.push` to have access to more
information. Leaving `localrepo.push` in place will let third party extensions
wrap it but it would never be called by `hg push` making the wrapping useless.
Therefore, the method is removed so that third party codes fail noisily and
get properly upgraded.
