Applies commit patches in Git repository for easier modification of patches.

Description of the Change

Adds option --commit-patches to apigentools templates command.

Alternate Designs

Possible Drawbacks

The template patches do not contain path prefix based on openapi-generator. It can be considered advantage as we had witnessed change of template folder from go-experimental to go.

Verification Process

Additional Notes

Update template patches:

$ cd templates/<lang>/<version>
$ git log --pretty=format:"%H:%s" --reverse | tail -n +2 | while IFS=: read -r commit file; do git diff $commit^..$commit > ../../../$file; done

Get list of template patches for a language:

$ cd templates/<lang>/<version>
$ git log --pretty=format:"- %s" --reverse | tail -n +2
