Update grape-entity to 0.6.0

The `repository_access_level` attribute doesn't exist in the 8-12-stable
branch so repository access cannot be restricted using this feature.

Fortunately we use `can?(user, :download_code, ref_project)` in
lib/banzai/reference_parser/commit_parser.rb and
lib/banzai/reference_parser/commit_range_parser.rb and this permission
already exists in 8-12-stable (it only depends on the project
`visibility_access`).

Honour issue and merge request visibility in their respective finders

This MR fixes a security issue with the IssuesFinder and MergeRequestFinder where they would return items the user did not have permission to see. This was most visible on the issue and merge requests page for a group containing projects that had set their issues or merge requests to "private".

This MR does not prevent references to repository files, since they are just markdown links and don't leak

Fix Safari displaying NaN for selected due date

## What does this MR do?

1. Stops using `Date.parse` to parse selected due dates.
2. Refactors DueDateSelectors to be more maintainable and readable

## Are there points in the code the reviewer needs to double check?

**To review the actual fix, look here:** https://gitlab.com/gitlab-org/gitlab-ce/commit/4ad43ac3a12902d7ea01dc09f8a361b01c21a0ee. It would be difficult to pick out from the overall diff.

## Why was this MR needed?

In Safari, the due date selector was displaying 'NaN' when a date is selected, which was being returned by `Date.parse`. Because `Date.parse` is implemented differently across browsers it's generally recommended to favor implicit Date parsing with the `Date` constructor. For more background on this, [see MDN on Date.parse](https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Global_Objects/Date/parse).

Also, the code for DueDateSelector was pretty messy, and its logic was very tightly coupled, so I refactored it. None of the basic logic changed, I just broke it up into smaller pieces and made it more OO.

Handle case where deployment ref no longer exists

## What does this MR do?

In 8.9, we didn't create keep-around refs for deployments. So it's possible that someone created a deployment (say, for testing), and then deleted the branch and all other references to that commit. That commit could then get GCed, and trying to view MRs on 8.11+ will show a 500. See https://gitlab.com/gitlab-org/gitlab-ce/issues/22655#note_16575020 for more details.

## Why was this MR needed?

If someone created a deployment on 8.9, then deleted all references to the commit for that deployment, we will throw an exception when checking if the deployment includes a commit.

Closes #22655.

Prevent flash alert text from being obscured when container is fluid

Fixes [a regression](https://gitlab.com/gitlab-org/gitlab-ce/commit/a2af7790) that causes the text within server-initiated flash *alerts* (not flash *notices*) to be obscured when `.container-fluid` is applied. It was reported in relation to a cherry-picking flash alert, but the problem occurs with all server-initiated flash alerts contained by a fluid container.

Note that as part of this fix, I combined some duplicate code and removed `.flash-text` & `.content-wrapper` selectors as they didn't seem to be necessary.

I manually tested JS-initiated Flash alerts to make sure this doesn't affect their appearance. I also grepped around for anything else that might depend on these styles. Everything checked out. But... can *you* see something this is going to break?

Affected users can't read flash alerts.

Use forked github-markup gem to enable python3 support with omnibus

Changes the version of `github-markup` gem we are using, to be the forked one with the changes to enable python3 support.
The change is backward compatible with users using Python 2, and will only be running with Python 3 in Omnibus (with the help of a custom patch we apply there).

Make sure backward compatibility isn't broken for source installs.

You need to make sure you pickup into stable this merge request as well (for omnibus): https://gitlab.com/gitlab-org/omnibus-gitlab/merge_requests/1015 as it's part of the fix, otherwise package will fail to build.

We had some regressions with .rst rendering that were fixed, but still some issues with encoding persisted (this MR will fix that). See: https://gitlab.com/gitlab-org/gitlab-ce/issues/21696
