Integrate with commitlint for zen status

Hi all,

I propose to read the commit lint configuration to adapt the cli to have a single configuration for both tools.
A use case:
- a user configured to enforce a scope in commitlint
- a user configured the scopes accepted in commitlint

The user expect to not be allowed to skip the "scope" step in commit lint, also the help message should show the scopes accepted.

Current situation: Nothing of this will happen and commitlint will fails wit the message built by commitzen cli.
