packaging: unify ovirt admin user email

[arso]

This patch changes default ovirt admin email address to one required
(hardcoded) by grafana so that oVirt SSO works when Keycloak integration
is disabled.

As discussed in private, I can see value in this patch, but do not have the full picture - can't say if it's risking upgrades or other flows, or how hard it is to achieve good-enough convenience without it - e.g. by (automatically?) creating another admin user in grafana (which IIRC is what we did until keycloak).

@didib You are absolutely right - I created that patch mostly to run it against OST.

If we do merge it, perhaps we should have a doc bug to update the text around "For this option, you need an operational local mail server configured on the Grafana machine", in the admin guide. I guess I phrased it generally enough, at the time, to accommodate also current patch, not mentioning that you should make mail to root@localhost approachable somehow (e.g. alias it to your own address or have a mail reader on the machine).

AFAIK nothing uses email address for admin@internal. This email address has been added only because of grafana, as it requires all users to contain valid address

So I'm OK to change to admin@localhost if needed, but I'd like to know why root@localhost is not working properly on grafana SSO

Let's convert it to regular patch and merge
