[apache/helix] -- [Part-2] Enable JDK 1.8 (backward) compatibility for 
meta-client (#2802)

We would like to provide a backward compatible support to our consumers 
where they also have an option to use JDK-8 compiled meta-client jar, if they 
have such a requirement. By default we will generate JDK-11 jars and JDK-8 jars 
using a classifier.

 new 1d47d6b51 [apache/helix] -- Add SetPartitionToError for participants 
to self annotate a node to ERROR state (#2792)
1d47d6b51 is described below

commit 1d47d6b51ee27764008685cf6ec76d4108915807
Author: Charanya Sudharsanan

[apache/helix] -- Add SetPartitionToError for participants to self annotate 
a node to ERROR state (#2792)

Co-authored-by: Charanya Sudharsanan 

What: An API endpoint that validates the incoming request and sends a state 
transition message to sets one or more partitions from any current state to 
ERROR state.

Why: Currently, the participants are unable to set a partition to an ERROR 
state explicitly when they seem to be stuck in a specific current state. The 
only way a replica can be set to ERROR is from within a state model. Having an 
endpoint to allow this behavior would allow the clients to call the 
resetPartition endpoint to set it back to INIT state and recover the replica. 
resetPartition works only on partitions in error state.

[apache/helix] -- Issue during onboarding resources without instances 
(#2782)

 When adding a new WAGED resource with a tag and without any instances 
against that tag, we are observing NPE coming from the system. To solve this 
issue we are adding a check in the ResourceComputationStage to have such 
resources excluded from the pipeline computation and only be considered when 
there are actual resource partitions (>0) to be assigned to the instances.

[apache/helix] -- Enable JDK-8 Build alsong with JDK-11 (#2775)

We would like to provide a backward compatible support to our consumers 
where they also have an option to use JDK-8 compiled helix-core jar, if they 
have such a requirement. By default we will generate JDK-11 jars and JDK-8 jars 
using a classifier.

The following commit(s) were added to refs/heads/master by this push:
 new fbefa6490 Change TopStateHandoffReportStage to be an Async Stage as it 
is the slowest stage in the pipeline. It can be run async since it does not add 
to ClusterEvent and simply computes and reports metrics. No following stages 
depend on it. (#2610)
fbefa6490 is described below

commit fbefa64909781d479ec486a93d22bba416322fb8
Author: Zachary Pinto 
AuthorDate: Thu Aug 31 20:10:13 2023 -0700

Change TopStateHandoffReportStage to be an Async Stage as it is the slowest 
stage in the pipeline. It can be run async since it does not add to 
ClusterEvent and simply computes and reports metrics. No following stages 
depend on it. (#2610)

In some cases TopStateHandoffReportStage is taking a very long portion of 
the total pipeline execution time. In order to speed up the total pipeline 
execution time, we will make TopStateHandoffReportStage async since it is 
simply computing metrics and reporting without adding to ClusterEvent.
