Comment 1 for bug 1583220

So this has come up before and I think we need to improve what we output when we raise here. I'm just not sure exactly how and what is needed here. I agree this isn't super helpful for debugging and requires too much reading into the details to figure it out.

Like, in this case it is saying the plugin is misconfigured and trying to import tests.tempest.plugin (from where ever the plugin is running) Like if it is the cinder plugin its trying to import tests/tempest/plugin.py from the cinder root which doesn't exist. I'm not sure what we need to also output on the error to make this more clear
