[PR] Stabilize TestInstanceOperation [helix]
zpinto opened a new pull request, #2715:
URL: https://github.com/apache/helix/pull/2715
### Issues
- [x] TestInstanceOperation was flaky, using TestHelper.verify should stabilize the test.
### Description
Stabilize TestInstanceOperation. clusterVerifier is evaluating to true once the partitionAssignment matches the expected value; however, it is before the TopState is transfered back to the SWAP_IN node. This can be fixed by using TestHelper.verify to check that states converge within TIMEOUT.
### Tests
- [x] TestInstanceOperation, ran 3 times and did not see any failures.
### Commits
- My commits all reference appropriate Apache Helix GitHub issues in their subject lines. In addition, my commits follow the guidelines from "[How to write a good git commit message](http://chris.beams.io/posts/git-commit/)":
1. Subject is separated from body by a blank line
1. Subject is limited to 50 characters (not including Jira issue reference)
1. Subject does not end with a period
1. Subject uses the imperative mood ("add", not "adding")
1. Body wraps at 72 characters
1. Body explains "what" and "why", not "how"
### Code Quality
- My diff has been formatted using helix-style.xml
(helix-style-intellij.xml if IntelliJ IDE is used)

testZoneIsolationWithInstanceTag is flaky due to GlobalRebalance failing to produce best possible state. This is because cache is being modified by ReadClusterDataStage when GlobalRebalance is running in async. This is expected possible behavior.
We will investigate way to mitigate this in the future.
