Embedding Grafana metrics panels in GFM

See merge request gitlab-org/gitlab!18285

Adds filters for supporting the ability to embed Grafana metrics
in GitLab Flavored Markdown. Adds a filter which identifies
references in GFM to the domain corresponding to a configured
GrafanaIntegration for the project.

Note: This is only available for Prometheus datasources which are
configured to be proxied through Grafana.

Presumably, these sizes will be *fairly* standardized so that they
don't mean different things in different places.

Fail if a test leaves the browser logged in

See merge request gitlab-org/gitlab!18978

All QA tests expect to be able to log in at the start of the test.

That's not possible if a test leaves the browser logged in when it
finishes. Normally this isn't a problem because Capybara resets the
session after each test. But it does that in an `after` block, so when
a test, like this one, logs in in an `after(:all) block, the browser
returns to a logged in state *after* Capybara has logged it out. And
then the next test will fail.

E.g.: https://gitlab.com/gitlab-org/gitlab/issues/34736

This adds a `config.after(:context)` block to fail if a test
leaves the browser logged in.

We've been seeing increased flaky failures due to the timeout
exceeding 3 seconds. With the additional regexp in

gotten worse:

```
1.376477   0.005843   1.382320 (  1.423449)
```

Previously it was:

```
