exclude maven check-style in eclipse, to suppress eclipse errors
support changing mode to disabled, ensuring things really are purged from memory; and allow HA tests based on RebindTestUtils/Fixture
better bookkeeping for scheduled tasks (counts go to 0 now), and set tags on scheduled tasks
switch incomplete tasks to be tracked by ID, rather than a simple count, so we can GC those which are interrupted (and so their afterEnd method is never called),
ensuring incomplete counts are accurate modulo interrupted-but-not-garbage-collected tasks; and log if tasks are removed while active
ensure feeds (and all entity tasks) are cancelled when entities are unmanaged, including in-memory test and an integration test with nginx; now it will GC entity tasks *after* fully unmanaged, but will cancel entity tasks *during* unmanage. also fixes nginx issue where it tries to reload conf immediately on rebind
a few minor tidies for GC'ing tasks and alerting on nginx reload/update failure
