This adds a method to Gitlab::GonHelper called
`push_frontend_feature_flag`. This method can be used to easily expose
the state of a feature flag to Javascript code. For example, using this
method we may write the following controller code:

    before_action do
      push_frontend_feature_flag(:vim_bindings)
    end

    def index
      # ...
    end

    def edit
      # ...
    end

In Javascript we can then check the state of the flag as follows:

    if ( gon.features.vimBindings ) {
      // ...
    }

Fixes https://gitlab.com/gitlab-org/release/framework/issues/17

Enable even more frozen string in lib/**/*.rb

Feature improved branch filter sorting

Instance SAML SSO e2e test

See merge request gitlab-org/gitlab-ce!22271

Add new sort option "most_stars" to "Group > Children" pages

See merge request gitlab-org/gitlab-ce!22121

When the job page is rendered we fetch the pipeline
endpoint to render the stages in the sidebar.
Without `.json` the response is cached, and when the
user goes back to the pipeline's page it renders the
json output instead of the Vue app

Revert GitLab Pages version to v1.1.0

See merge request gitlab-org/gitlab-ce!22277

Project deletions were failing with "Can't modify frozen hash" because:

1. Project#remove_exports was called in the after_destroy hook
2. This would remove the file and update ImportExportUpload
3. ImportExportUpload#save would attempt to write to a destroyed model

To avoid this, we just check if ImportExportUpload has been destroyed
before attempting to save it.

This would have a side effect of not running after_commit hooks to delete the
repository on disk, making it impossible to delete the project entirely.

Closes #52362

This works around the problem with domains not working
due to https://gitlab.com/gitlab-org/gitlab-pages/issues/170.

Adds a new QA test and the required page objects and related changes

Filesystem performance can have a big impact on overall GitLab
performance, especially for actions that read or write Git
repositories. This information will help benchmark filesystem
performance against known good and bad real-world systems.
