Anton Studenov 9d0ed2cc7d Add performance degradation SLA plugin
This adds SLA plugin that finds minimum and maximum duration of
iterations completed without errors during Rally task execution.
Assuming that minimum duration is 100%, it calculates
performance degradation against maximum duration.

Example config:
  sla:
    performance_degradation:
      max_degradation: 75

Spec: sla_pd_plugin
