One test failure seems to be related:
```
java.lang.AssertionError: class org.apache.hadoop.ozone.OzoneConfigKeys
class org.apache.hadoop.hdds.scm.ScmConfigKeys class
org.apache.hadoop.ozone.om.OMConfigKeys class
org.apache.hadoop.hdds.HddsConfigKeys class
org.apache.hadoop.ozone.s3.S3GatewayConfigKeys has 1 variables missing in
ozone-default.xml Entries: hdds.scm.chillmode.healthy.pipelie.pct
expected:<0> but was:<1>
```
ozone-default.xml should be updated with the new configuration.

> This Jira is to implement one of the chill mode rule.
> h2. Pipeline Rule with configurable percentage of open pipelines with all
> datanodes reported:
> h2. In this rule, we consider when at least 10% of the pipelines have all 3
> data node's reported (if it is a 3 node ratis ring), and one node reported if
> it is a one node ratis ring. (The percentage is configurable via ozone
> configuration parameter).
>
> This rule satisfies, once the SCM is restarted, and after exiting chill mode,
> we have enough pipelines to give for clients for writes to succeed.
