Subject: [PATCH 43/93] [sosreport] log plugin exceptions to a file

Add exception logging for the Plugin.postproc() method and move
plugin exceptions into a separate per-plugin log file. This is
less cluttered than pushing a multi-line traceback through the
soslog.error logger and matches the behaviour of older releases.
