* Remove the description header. It is confusing because commit message body goes before it
* Explicitly require human-readable changelogs
* Explicitly require links to the external changelogs/diffs
* Introduce the pull-request template.
This change xplicitly sets expectations from pull requests.
Reason:
* Highlight the need in autotests and JIRA issues for bugfixes
* ask PR creators to propose the changelog entries for their changes.
* Provide hints about referencing people
* Move the pull request template to .github
