Cannot add Shahar as reviewer in Gerrit

[Nir Soffer]

Hi infra,

Can you fix Shahar account on gerrit, so we can add him as reviewer
to patches?

I get this error when trying the add Shahar to https://gerrit.ovirt.org/56574

Shahar Havivi <xxx at redhat.com> does not identify a registered user or group

This usually happens when your account was created using gmail account
and you login using redhat account (or the other way around).

Thanks,
Nir
