releasenotes: add custom admonitions support for release notes
By default, the extension has default sections like fix, feature, perf etc.. This
patch allow user to add support for custom admonition. In order to add a custom
admonition, one needs to have a .hgreleasenotes file inside the repository. All the
custom directive with name specified under the tag [sections] will be
usable by the extension. One important thing to keep in mind is if there exists any
custom admonitions with same key as default then they will override the default ones.
