Update rspec guidelines for aggregating failures

See merge request gitlab-org/gitlab!19512

- Typically when we write tests, we try to only use one
  expectation per test.  However, that isn't always optimal.
  So in those cases where we have more than one expectation,
  we should try to use :aggregate_failures in order to see
  all the failures in a test block at once and not have to
  piecemeal through it as we get each to pass.

Merge branch '34418-admin-setting-integrations-incorrectly-report-validation-errors-in-ui' into 'master'

Remove unrelated errors from individual integrations

Closes #34418

See merge request gitlab-org/gitlab!18814

- before when any of the integrations had a form error,
  all of them would display that message block.
- now we have contained those error messages to the areas
  they affect.

Increase certmanager install timeout

See merge request gitlab-org/gitlab!19447

We have been getting reports from users that the cluster
issuer is not ready prior to timing out, failing the
installation. Since this time is primarily spent on the
cluster and not in Sidekiq, we can probably afford to wait
a bit longer.

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.
