The V2 Gaudi plugin loader is fragile in that it can sometimes mysteriously
fail if dynamic libraries have been loaded during the python part
of initialization.  We were doing this to pick up the dictionaries
we needed.  Restructure this as an algorithm in order to defer the
dictionary loading to initialize().

Do not use a whitespace in the COOL tag name. Otherwise one cannot
easily inspect the file with AtlCoolConsole.

Fix tests to work properly with new file catalog implementation.
  - Always delete catalog at the start of a run.
  - Don't write a PoolFileCatalog.xml; always rename to a test-specifiic name.
  - Update reference files correspondingly.

Fixes ATN failures.

SGInputLoader is now configured centrally.  Don't add it in the individual
test JOs.

Update reference files for changes in conditions handling in Gaudi 29.

Add test of a conditions algorithm, and of reading a derived conditions type
via a base class.
