Pass commit data to ProcessCommitWorker This changes `ProcessCommitWorker` so that it takes a Hash containing commit data instead of a commit SHA. This means the worker doesn't have to access Git just to process a commit message (and other data it may use). This in turn should solve the problem of ending up with 15 000-something jobs in the `process_commit` queue that take forever to process. See merge request !7744
Resolve "User-generated permalink IDs collide with GitLab interface" ## What does this MR do? Prevents ID values automatically generated by headers in [GitLab Flavored Markdown](https://github.com/gitlabhq/gitlabhq/blob/master/doc/user/markdown.md#header-ids-and-links) from colliding with IDs used elsewhere in the GitLab interface. This can cause confusion when, for instance, a selector looks for a merge request tab with `id="pipelines"` and there is a header with the same ID earlier in the DOM. How this works: * All header IDs generated with GitLab Flavored Markdown are namespaced with `id="user-content_foo"` * All anchor links which point to these IDs continue to use the non-namespaced hash `<a href="#foo">...</a>` * When a page is loaded or when the `hashchange` event is triggered, javascript will automatically search for `#user-content_foo` if `#foo` cannot be found, and scroll to that position instead. ## Before  ## After:   ## Does this MR meet the acceptance criteria? - [x] [Changelog entry](https://docs.gitlab.com/ce/development/changelog.html) added - Tests - [x] Added for this feature/bug - [ ] All builds are passing - [x] Conform by the [merge request performance guides](http://docs.gitlab.com/ce/development/merge_request_performance_guidelines.html) - [x] Conform by the [style guides](https://gitlab.com/gitlab-org/gitlab-ce/blob/master/CONTRIBUTING.md#style-guides) - [x] Branch has no merge conflicts with `master` (if it does - rebase it please) - [x] [Squashed related commits together](https://git-scm.com/book/en/Git-Tools-Rewriting-History#Squashing-Commits) ## What are the relevant issue numbers?

By passing commit data to this worker we remove the need for querying the Git repository for every job. This in turn reduces the time spent processing each job. The migration included migrates jobs from the old format to the new format. For this to work properly it requires downtime as otherwise workers may start producing errors until they're using a newer version of the worker code.
