Adds ability to configure frequency for pod termination via annotation.
Closes #20
Allows specifying a new command line flag,
--termination-frequency-annotationwhich sets the annotation to look for and use to calculate the approximate frequency at which to terminate a given pod. Follows the examples given in #20, such as...chaos.alpha.kubernetes.io/frequency=2/dayfor "kill this twice per day"chaos.alpha.kubernetes.io/frequency=10/hourfor "kill this ten times per hour"chaos.alpha.kubernetes.io/frequency=1/weekfor "kill this once a week"chaos.alpha.kubernetes.io/frequency=0.5/dayfor "kill this pod once every two days"Pods without the annotation are assumed to always be candidates for termination. The
--max-killflag also still applies and will potentially limit how frequently a pod is terminated if it isn't high enough.
