Issue:
Add an option to disable changelog generation
Thanks for stopping by to let us know something could be better!

**PLEASE READ**: If you have a support contract with Google, please create an issue in the [support console](https://cloud.google.com/support/) instead of filing on GitHub. This will ensure a timely response.

 **Is your feature request related to a problem? Please describe.**

I'm frustrated that Release Please always generates and commits a `CHANGELOG.md` file. It is the developer's decision to keep that file or not, and it must not be enforced by this tool. For instance, I find changelog files to be redundant and provide little use to the end consumers of my software. I use GitHub releases as the changelog, which Release Please already fills in using the same content as the changelog. 

 **Describe the solution you'd like**

A `--disable-changelog` boolean flag which, when set to `true`, skips the changelog generation phase altogether. 

 **Describe alternatives you've considered**

1. Setting `changelog-types: ""`, gets ignored by the tool.
2. Setting `changelog-path` to the path ignored in Git. No effect either.




Discussion:
@unjust: I'm using release-please with a monorepo and I prefer one changelog for the entire project, and not for the subprojects.
I've tried `"changelog-path": "",` `"changelog-path": false,` in the `config.json` in order to skip it in subprojects, but its still generated.
also adding `CHANGELOG.md` to my `.gitignore` doesnt stop the pull request from adding them, maybe oktokit bypasses the gitignore? 🤷 @chingor13: An option to disable changelog generation is feasible, but not something we're planning on implementing. We would welcome a pull request to potentially add the feature.@kettanaito: @chingor13, I'd love to help you ship it. Just, let me know what kind of API you find best to disable changelog generation. I proposed `--disable-changelog` above, do you have any opinions on that? We can also use `--no-changelog`, following the `--no` flags convention for negative expected behaviors. 

If we can agree on the API here, I will try to pen a pull request this/next week. Thanks! 
@chingor13: Thanks!

I think we want this as a manifest config option (schema: https://github.com/googleapis/release-please/blob/main/schemas/config.json). The CLI option is an optional inline interface into specifying a manifest config (but we prefer folks configure a manifest config).

As for the naming of the option, I would suggest `skip-changelog` to match `skip-release` and `skip-snapshot` configuration options.@unjust: +1 on the manifest option. It would be nice to be able to skip-change logs on packages in a repo but still keep the overall changelog. I think the manifest would allow this granularity.@unjust: @kettanaito do you have a branch for this work yet ? 👀 need a hand ?@aabouzaid: @unjust I see that you already have some WIP ... did you open a PR for it? (or willing to continue working on it?)@stan-stately: I implemented it here: https://github.com/googleapis/release-please/pull/2535. please take a look
