Ensure we create the secrets at the right time

Closes #53621

See merge request gitlab-org/gitlab-ce!22938

Previously, we just fetched the latest commit for the given branch when
presenting the resulting commit, but because something could have been
committed to that branch between the time we cherry-picked and the time
we render the result, the wrong commit could have been presented.

Now, we fetch the commit object with the commit SHA returned by the
commit change service, which should always be the correct commit.

In `deploy`, if the previous deployment failed, we delete/cleanup all
the objects related to the release, including secrets. The problem is
that if we create the root password before that, it will be then
recreated during the deploy with a random value!

By creatigng the secret just before actually deplying a new release, we
ensure that it won't be overriden.

I have also extracted an issue in
https://gitlab.com/gitlab-org/gitlab-ce/issues/53738 to surface these
errors to users but now I am just fixing the bug where
kubernetes_namespace is undefined while handling this error

There is no reason to specially handle 404 here. We only handle 404
specifically if we are fetching something and want to return `nil` if
404.  This does not apply here.
