Upgrade to custom pod autoscaler v0.10.0

[v0.10.0] - 2020-01-22

Added

• Set up API to be versioned, starting with v1.
• Can now manually trigger scaling through the API.
• Added extra run_type flag, api_dry_run, for evaluations through the API in dry_run mode.
• Added apiConfig to hold configuration for the REST API.
• Added extra configuration options within apiConfig.
  • enabled - allows enabling or disabling the API, default enabled (true).
  • useHTTPS - allows enabling or disabling HTTPS for the API, default off (false).
  • certFile - cert file to be used if HTTPS is enabled.
  • keyFile - key file to be used if HTTPS is enabled.

Changed

• The command for shell methods is now an array of arguments, rather than a string.
• The /api/v1/evaluation endpoint now requires POST rather than GET.
• The /api/v1/evaluation endpoint now accepts an optional parameter, dry_run. If dry_run is true the evaluation will be retrieved in a read-only manner, the scaling will not occur. If it is false, or not provided, the evaluation will be retrieved and then used to apply scaling to the target.
• Moved port and host configuration options into the apiConfig settings.

[v0.9.0] - 2020-01-19

Added

• Support for other entrypoints other than /bin/sh, can specify an entrypoint for the shell command method.
• Add logging library glog to allow logging at levels of severity and verbosity.
• Can specify verbosity level of logs via the logVerbosity configuration option.

Changed

• Can scale ReplicaSets, ReplicationControllers and StatefulSets alongside Deployments.
• ResourceMetrics fields have resourceName and resource rather than deploymentName and deployment. In JSON this means that only the resource name will be exposed via field resource.
• Uses scaling API rather than manually adjusting replica count on resource.
• Matches using match selector rather than incorrectly using resource labels and building a different selector.
