Escape HTML nodes in builds commands in ci linter

This MR removes call to `simple_format` that behaves like `String#html_safe`, thus it passes unescaped HTML tags to the view.

Enforce the fork_project permission in Projects::CreateService

Projects::ForkService delegates to this service almost entirely, but needed one small change so it would propagate create errors correctly.

CreateService#execute needs significant refactoring; it is now right at the complexity limit set by Rubocop. I avoided doing so in this commit to keep the diff as small as possible.

Allow the Rails cookie to be used for API authentication

Makes the Rails cookie into a valid authentication token for the Grape
API, and uses it instead of token authentication in frontend code that
uses the API.

Rendering the private token into client-side javascript is a security
risk; it may be stolen through XSS or other attacks. In general,
re-using API code in the frontend is more desirable than implementing
endless actions that return JSON.

Closes #18302

Exclude some pending or inactivated rows in Member scopes

An unapproved request or not-yet-accepted invite should not give access rights. Neither should a blocked user be considered a member of anything.

One visible outcome of this behaviour is that owners and masters of a group or project may be blocked, yet still receive notification emails for access requests.

lib/backup: fix broken permissions when creating repo dir

## What does this MR do?

This MR fixes an issue where gitlab:backup:restore will not work because the repositories directory is set up with bad permissions. The bad permissions will prevent access to the repositories by the git user, causing all kinds of troubles (e.g. gitlab-shell won't install hooks).

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

## Why was this MR needed?

Rake task gitlab:backup:restore would complete successfully, but gitlab:check will report errors and gitlab cannot access repos.

## Screenshots (if relevant)

* repositories.old.1472478726 was created without the fix
* repositories was created with the fix

Fix attribute inclusion import/export config ignored in some cases

In the `import_export.yml` file we define the inclusion of some of the attributes. For some reason, this isn't working in certain cases - very unfortunate this includes `user`. This has been introduced in 8.10.3.
