SidekiqScheduler::Manager enormous inspect output

[Evan Huus]

Trying to inspect an instance of SidekiqScheduler::Manager produces around 5k lines of output on our system because it holds references to a bunch of other complex objects and eventually starts printing large chunks of internal sidekiq and rails objects.

This is doubly annoying because with debug-logging enabled on sidekiq, the SidekiqScheduler::Manager instance is inspected/logged at sidekiq startup.

It's easy enough to monkey-patch with something like:

module SidekiqScheduler
  class Manager
    def inspect
      "SidekiqScheduler::Manager"
    end
  end
end

But there should probably be some debugging information included, and I don't know what values are worth logging here.
