[pyramid] Drop module-level cache and cleanup looping tasks in tools And use a LRU cache over cached_build_user function. This looping task is problematic because it would not be run from within a WSGI application which does not have a repository with a tasks manager. This pulls an explicit dependency on 'repoze.lru' but it's not a big deal since pyramid already depends on this. RPM spec file not update since it does not even mention pyramid...
