Add a option to skip the command if the file list is empty

[robsonpeixoto]

⚡ Summary

Sometimes is very annoying compile the project just because you change the Dockerfile or a README.
Now the Command is only skipped if the {files} template is used, but sometimes is not possible to use it on the run configurations.

Behavior and configuration changes

Add a configuration to skip the command if the list of files is empty. Example:

pre-commit:
  parallel: true
  commands:
    compile_1st_suggestion:
      glob: "*.{ex,exs}"
      run: mix compile
      skip_empty: {staged_files}
      env:
        MIX_ENV: prod
    compile_2nd_suggestion:
      glob: "*.{ex,exs}"
      run: mix compile
      skip:
        - is_empty: {staged_files}
      env:
        MIX_ENV: prod

Hey @robsonpeixoto , I'm thinking of this for quite a long time. It feels like if you've specified the glob or exclude you definitely want to skip command if files are missing. For pre-commit hook it is {staged_files}, for pre-push it is {push_files}. What do you think if this happens implicitly? I think that's what many people expect as a default behavior without explicit skip option. 🤔
