Previously the search form just wasn't including any params that had previously been set, so when you filtered by name, it would reset all the params & therefore ignoring the archived param

Closes #28007

The query parameter `membership` should be more self-explaining.

The `projects/:id/pipelines` exposed a lot of extra details
that are superfluous and it was taking extra resources to fetch them.

To get more details about a pipeline, use
`projects/:id/pipelines/:pipeline_id`.

This reverts commit 07717744.

Use strings for the ApplicationSetting properties:
 - restricted_visibility_levels
 - default_project_visibility
 - default_snippet_visibility
 - default_group_visibility

Because environments also expose the project, ensure the projects are
exposed as they were before in API v3.

Instead of exposing the VisibilityLevel as Integer, expose it as
String `visibility`.

jQuery UI is no longer used anywhere so say goodbye to it from package.json & Gemfile

See https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/9245

Instead of exposing the VisibilityLevel as Integer, expose it as
String `visibility` for Project and ProjectSnippet.

Filter queries also accept the `visibility` as String instead of
`visibility_level` as Integer.

Also remove the `public` boolean.

- Also remove a redundant test
