Add support for [skip ci]

[marcosschroh]

Hi,

I was thinking and maybe could be a good feature to add the option [skip ci] to the commit message in order to skip the CI process. Most of CI tools like CI Gitlab, Jenkins explore the commit message and If it contains [ci skip] or [skip ci], using any capitalization, the commit will be created but the pipeline will be skipped.

Current situation: We want to bump a version after we detect some changes on the master branch. This process can be done by the CI process, so after the bumping, a new commit is generated and push to master branch. This latest commit will trigger again the CI unless [skip ci] is found in the message.

So, maybe the bump command could have an extra option like:

cz bump --skip-ci

generating: version 0.6.0 → 0.7.0 [skip ci] commit message.

The [skip ci] message could be configured as well in order to support multiple CI conventions tools. By default, should be [skip ci].

Make sense?

What do you think about custom commit message instead?
Similar to the way the tag template works.

In the config you could set:

[tool.commitizen]
message = "bump: $old_version to $new_version [skip ci]"

My concern is that you might want to skip an specific CI see here

Make sense as well and will work.

My concern is that you might want to skip a specific CI:

Yes, this is why I was thinking that the "[skip ci] message" could be configured in order to support different CI like [skip travis].

Now the question is whether you as a developer want to have both options at the same time and probably the answer is no.

So, closing the issue and may be reopened in the case that is needed.

Don't close it, I still have to add the feature. This is the reference

I thought that the library already has support for custom commit messages, my bad. So, this feature is totally need it!
