This one should be removed, we do not maintain 4.3 anymore

This is obsoleted by ost-images and el8 runs, as you do locally. We
are waiting to get rid of el7 jenkins slaves and mock env there

Should be removed

Will be obsoleted once network suite completes move to ost-images/el8

This should be removed

Progress with our CI env is very slow indeed

Yes, ost-image based runs are way more reliable. Currently this
applies only to master basic suite.
