Add a way of reusing a commit message

I'd like to be able to reuse a commit message that was just created by the `commitizen` CLI. The use case: sharing the same message in two different repositories, without having to be prompted for all the questions again.

Since the commit is done under the hood, for instance, the autocompletion/autosuggestion from zsh can't handle it. Perhaps adding the commit to the .bash_history would work? Not sure. Another solution that comes to my mind as of now would be to add a last option called "Copy to clipboard? [Y/n]", then if yes, it could be reused as well in other repositories/terminal tabs.

Nenhum arquivo ou teste é mencionado, e a issue deixa em aberto a escolha da implementação. Comece rastreando o fluxo da CLI do commitizen que cria a mensagem de commit e, em seguida, determine e teste um caminho de reutilização compatível cujo resultado funcione em outro repositório ou terminal.
