Adds extra guards for plugin imports

[skrawcz]

We should probably just blanket catch all errors -- but not doing that right now. Hamilton fails to be imported in a spark serverless environment because there is some interaction with DLT that databricks doesn't like.

So catching more exceptions -- and shoe horning it into an import error.
