Vivek Bagade c6b87841ce Added a new method that uses pod packing to filter schedulable pods 
filterOutSchedulableByPacking is an alternative to the older
filterOutSchedulable. filterOutSchedulableByPacking sorts pods in
unschedulableCandidates by priority and filters out pods that can be
scheduled on free capacity on existing nodes. It uses a basic packing
approach to do this. Pods with nominatedNodeName set are always
filtered out.

filterOutSchedulableByPacking is set to be used by default, but, this
can be toggled off by setting filter-out-schedulable-pods-uses-packing
flag to false, which would then activate the older and more lenient
filterOutSchedulable(now called filterOutSchedulableSimple).

Added test cases for both methods.

Alex Price 4ae7acbacc add flags to ignore daemonsets and mirror pods when calculating resource utilization of a node 
Adds the flag --ignore-daemonsets-utilization and --ignore-mirror-pods-utilization
(defaults to false) and when enabled, factors DaemonSet and mirror pods out when
calculating the resource utilization of a node.

Steve Scaffidi 56b5456269 Fixing nits: renamed newPodScaleUpBuffer -> newPodScaleUpDelay, deleted redundant comment 
Change-Id: I7969194d8e07e2fb34029d0d7990341c891d0623
 2018-09-17 10:38:28 -04:00
Steve Scaffidi 33b93cbc5f Add configurable delay for pod age before considering for scale-up 
- This is intended to address the issue described in https://github.com/kubernetes/autoscaler/issues/923
  - the delay is configurable via a CLI option
  - in production (on AWS) we set this to a value of 2m
  - the delay could possibly be set as low as 30s and still be effective depending on your workload and environment
  - the default of 0 for the CLI option results in no change to the CA's behavior from defaults.
