Creates a new Climber instance, optionally yielding the instance for
 configuration if a block is given

   Climber.new('beanstalk://localhost:11300', 'stalk_climber')
     #=> #<StalkClimber::Job beanstalk_addresses="beanstalk://localhost:11300" test_tube="stalk_climber">
 :call-seq:
   max_job_ids() => Hash{Beaneater::Connection => Integer}

 Returns a Hash with connections as keys and max_job_ids as values

   climber = Climber.new('beanstalk://localhost:11300', 'stalk_climber')
   climber.max_job_ids
     #=> {#<Beaneater::Connection host="localhost" port=11300>=>1183}
