support CHANGELOG generating hook

Is your feature request related to a problem? Please describe. In shipjs, CHANGELOG is generated with conventional-changelog-cli. CHANGELOG generation can be customized by setting conventionalChangelogArgs.

However, if CHANGELOG can be generated by another way than conventional-changelog-cli, it may be convenient to use other tools (e.g. lerna-changelog).

Describe the solution you’d like

module.exports = {
  generateChangelog: ({ config }) => {
    // something to do ...
  }
}

Additional context PR-based changelog generator https://github.com/lerna/lerna-changelog

@eunjae-lee Thank you for your workaround!

I’ve checked shipjs codes and behavior. I hope nextVersion argument of beforeCommitChanges, because it’s convenient as meta info with changelog generator.

And also, I’ve noticed the changelog generator have some different format. e.g.

• lerna-changelog: https://raw.githubusercontent.com/lerna/lerna-changelog/master/CHANGELOG.md
• converntional-changelog: https://raw.githubusercontent.com/algolia/shipjs/master/CHANGELOG.md

So, In GitHub release of shipjs trigger, I need changelog extraction hook. In this code, changelog is extracted by getChangelog. I hope it can be customized with the getChangelog hook.
