Prepare for v4.16.0 release

[blampe]

Added

• clusterIdentifier configuration can now be used to manually control the replacement behavior of a provider resource. (Add clusterIdentifier configuration to control provider lifecycle #3068)

• Pod errors now include the pod's last termination state, as well as the pod's termination message if available. (Upgrade cloud-ready-checks #3091)

  The pod's termination message can be helpful in CrashLoopBackOff situations but will only be reported if it was correctly configured.

  By default, the pod's termination message is read from /dev/termination-log. This location can be configured with terminationMessagePath.

  Use terminationMessagePolicy: FallbackToLogsOnError to use the pod's logs as its termination message.

• Documentation is now generated for all languages supported by overlay types. (Define Supported Languages for Overlay Resources #3107)

Fixed

• Updated logic to accurately detect if a resource is a Patch variant. (Enhance detection logic for patch variants #3102)
• Added Java as a supported language for CustomResource overlays. (Add java as supported language for CustomResource overlays #3120)
• Status messages reported during updates are now more accurately scoped to the
  affected resource. (Fix pod info reporting #3128)
• PersistentVolumeClaims with a bind mode of WaitForFirstConsumer will no
  longer hang indefinitely. (Fix endless PVC await #3130)
• [java] Fixed an issue where child resources could not be registered by Chart v4. (Child resource cannot be registered by Chart v4 (Java SDK) #3119)
