Epic Name:generic Exceptions
Description
There are a lot of except Exception blocks in our code. These blocks often just swallow the error, either logging a message or just continue-ing without saying anything. In almost every case (I can't prove it's every case without further exploration), we should only catch a very specific and short list of exceptions. The same applies to except lsst.pex.exceptions.Exception and except pexExcept.Exception.
I'm making this an epic as I started filling in the components list and ended up with just about every LSST owned package, so I figure this is best done on a package-by-package basis, or at least on groups of packages.
Filing as critical, as we already know of cases where this bug has hidden other problems (e.g. DM-13803).
