See

• https://github.com/Jimdo/changelogrc-spec
• add custom preset conventional-changelog#146

.changelogrc and package.json[changelog] could serve as config picked up by a whole family of tools, conventional-changelog-lint merely being one of them.

This would involve

• working with https://github.com/Jimdo/changelogrc-spec to extend the spec
  • with more configuration keys
  • with a wildcard extensible object carrying tool-specific configuration
  • with a notion of being located in package.json, think like ava, xo
• deprecating .conventional-changelog-lintrc
