This merge request was originally introduced in
https://gitlab.com/gitlab-org/gitlab/-/merge_requests/40026 but reverted
in https://gitlab.com/gitlab-org/gitlab/-/merge_requests/40245. We fix
the issue it caused by using `Gitlab::Redis::SharedState.url`, which
handles the differences between the GDK and CI `resque.yml`
configuration formats.

We started using Workhorse in feature tests, but no `config.toml` was
 provided. As a result, we missed a startup issue that could have been
caught by testing the config loading.

A small subset of Workhorse functionality also relies on Workhorse and
Rails sharing a Redis database. If we configure it here, we can enhance
the runner API testing in rails to ensure it behaves as expected.

This replaces all the usages of ~/vue_shared/components/icon.vue with
the corresponding GitLab UI component for all remaining ee/ components.

In a previous MR [0] we already replaced the internal implementation
with the GitLab UI component. This should allow us to migrate all usages
without any test failures relating to the differences in their
implementation.

The actual deletion of the file will be done in a follow-up in case we
have missed an instance or someone introduces a new one in the
meanwhile.
