Moving from #18 also awesome works in #45 by @leo91000 and #83 by @aa900031

@itpropro: Provide some way to generate changelogs only for one or more specific subfolders/repos in a monoprepo structure.

These are smaller tasks breakdown in order to support mono repos progressively since this is a rather big change in changelogen.

• Configurable git commit template (Custom commit message like [skip ci] #82)
• Monorepo utils (workspace (monorepo) utils pkg-types#117)
• Expose a new workspaces config object (auto-detected with resolveWorkspace from pkg-types)
• A new subDir config defaulting to / and when is set, filters commits only relevant to this subpath and also operates package.json and CHANGELOG.md in {rootDir}/{subDir} for updating
• Update CLI --release to use workspace config when is set/detected and operate release on each monorepo project with baseDir set (using sorted/ordered graph resolved by pkg-types)
• Extend scopeMap (auto added scopes using scope map config #86) with workspace config to automatically apply scoped changeloges

Note: PRs are more than welcome to implement each task. If you see an improvement in the roadmap for implementation please comment below. 🙏🏼
