Curb the number of constructor arguments to Handler classes

[jirkadanek]

Currently, we have

  class ReceiverHandler < Handlers::SRCommonHandler

[...]

    def initialize(
      broker,
      log_msgs,
      count,
      process_reply_to,
      browse,
      sasl_mechs,
      exit_timer=nil
    )

[...]

The argument count is going to go up as we are adding more options, likely approaching 20 or even more. This should be rewritten somehow.

Possibly pass the options object in there directly.

Yes, this is in plan.
