CA certificates package

Hi, as we are slowly fading out FreeIPA I renamed the "ca-certificates-freeipa-opensuse" package to "ca-certificates-opensuse". The new package obsoletes the old one, meaning if you have the openSUSE:infrastructure repository installed on a machine, you will see the replacement happen automatically during your next up/dup. Whilst at it, I also pushed the package to a new dedicated project, openSUSE:infrastructure:CA [1], in addition to openSUSE:infrastructure. This might be useful if you want to keep the root certificate up to date without keeping our big repository on your workstation. Note that no source/certificate files were changed.
