Improve cleanup of gpg-homedirs

See merge request gitlab-org/gitlab!19311

The `gpg-agent` that could have been spawned here dies when it sees
it's socket disappear.

However, sometimes it seems like we fail to delete the homedir,
causing the `gpg-agent` to live on forever. We've noticed that the
deletion failed in
http://gitlab.com/gitlab-org/gitlab-foss/issues/36998: there was a
race condition during the deletion where `gpg-agent` would still be
modifying files while we've already called `FileUtils.remove_entry`.

This will attempt to delete the directory multiple times, at least 0.1
seconds apart. This is a naive way of trying to make sure
we clean up the homedir and count on `gpg-agent` to see that and make
itself go away.

On a web node we'll attempt for at most 0.5 seconds to clean up the
directory before failing. In a sidekiq process we'll attempt the
deletion for up to 2 seconds.

When the cleanup fails, we will now track that exception in
Sentry to gain some visibility.

This also adds counters for the creation and deletion of tmp
keychains, which we should be able to correlate to the nubmer of
zombie `gpg-agent` processes.

Expose cycle analytics summary separately

See merge request gitlab-org/gitlab!19229

This change exposes the summary counts for group level cycle analytics
via a separate endpoint while making sure the old CA implementation is
still working.

This allows the flag to be referenced in other portions of the app
(coming soon), such as issues, MRs and epics.

Setting a long-term cache header works fine when not using object
storage, or when using object storage with proxy_download enabled. When
using object storage _without_ proxy_download, we send a redirect that's
cached for six months to a signed URL in object storage, but the signed
URL only works for ten minutes. So once those ten minutes are up, the
browser will keep following the (cached) redirect to a dead link.

In future, we could be more sophisticated by setting the TTL based on
the settings we're using. For now, just set this back to the pre-12.4
state of not caching content for longer than 5 minutes.
