Alerts for the GitLab-managed app Prometheus are updated via helm.
Prior to this change, when alerts were updated, all helm values would
receive the current contents of `values.yaml`, with the `alerts` section
overridden, or falling back to the default chart values.

This meant that any time we made changes to `values.yaml` affecting
component versions (e.g. the versions of prometheus or alertmanager),
those would trigger a deployment of those component in the cluster,
potentially breaking the prometheus installation.

This was a very real problem, since we currently have hardcoded versions
of both prometheus server and alertmanager in `values.yaml`, and would
like to update the chart and remove the hardcoded versions in a single
change.

With this change, alert updates no longer take any values from
`values.yaml`; instead they only update alerts. We avoid reverting to
default chart values by using helm's `--reuse-values` flag instead of
the `--reset-values` flag.

Fix :container_expiration_policy Import

See merge request gitlab-org/gitlab!21753

`:container_expiration_policy` was not imported as was not added into
UNIQUE_RELATIONS and EXISTING_OBJECT_CHECK hashes.
These hashes are very implicit and undiscoverable for the developer
who is adding new relation so they don't even know that the Import will
not be succeed.

Guest users should not be able to delete project snippets

See merge request gitlab-org/gitlab!20477

Example scenario:
A user with developer access creates a snippet and as the author is able
to update and delete the snippet. This user is then demoted to guest in
the project, but keeps the access to update and delete (as the author).

This new rule prevents the access to update and delete the snippet for
the author if their access level is less than reporter. Those author
users can still see the snippet and add comments.

This moves the current sanitization specs to a shared example, so we can
re-use them for broadcast message sanitization and be sure to not
introduce a XSS vulnerability.

Adds the ability to style links in broadcast messages and use line
breaks to format messages.
