CB-14462. Don't create UserSyncPoller bean

The UserSyncPoller is part of the polling automated usersync
solution (CDPCP-659). This approach was superceded by workload iam
and is not needed anymore.

The poller retrieves all Stacks with a spoecified DetailedStackStatus.
The stack status is stored in a separate table from the stack.
The hibernate query to return the stacks is rather inefficient. The
UserSyncPoller is disabled in lieu of optimizing the query.
