feat: Pass down changelog notes configuration to changelog writer

Feature is somehow related to #1802, or at least comes from the same issue with `CHANGELOG.md`.

Currently it possible to pass those params to control how changelog file looks like
```
changelogSections?: ChangelogSection[];
changelogPath?: string;
changelogType?: ChangelogNotesType;
changelogHost?: string;
```
but we have 0 control over templates themselves

It would be great to have an ability to pass down to the changelog writer additional parameters
```
mainTemplate
headerPartial
commitPartial
footerPartial
partials
```
see [docs](https://github.com/conventional-changelog/conventional-changelog/tree/master/packages/conventional-changelog-writer)

Current solution to my problem with prettier is to add `.prettierignore` configuration.
